/**
* GRegexCompileFlags:
* @G_REGEX_CASELESS: Letters in the pattern match both upper- and
* lowercase letters. This option can be changed within a pattern
* by a "(?i)" option setting.
* @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting
* of a single line of characters (even if it actually contains
* newlines). The "start of line" metacharacter ("^") matches only
* at the start of the string, while the "end of line" metacharacter
* ("$") matches only at the end of the string, or before a terminating
* newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When
* #G_REGEX_MULTILINE is set, the "start of line" and "end of line"
* constructs match immediately following or immediately before any
* newline in the string, respectively, as well as at the very start
* and end. This can be changed within a pattern by a "(?m)" option
* setting.
* @G_REGEX_DOTALL: A dot metacharacter (".") in the pattern matches all
* characters, including newlines. Without it, newlines are excluded.
* This option can be changed within a pattern by a ("?s") option setting.
* @G_REGEX_EXTENDED: Whitespace data characters in the pattern are
* totally ignored except when escaped or inside a character class.
* Whitespace does not include the VT character (code 11). In addition,
* characters between an unescaped "#" outside a character class and
* the next newline character, inclusive, are also ignored. This can
* be changed within a pattern by a "(?x)" option setting.
* @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is,
* it is constrained to match only at the first matching point in the
* string that is being searched. This effect can also be achieved by
* appropriate constructs in the pattern itself such as the "^"
* metacharacter.
* @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern
* matches only at the end of the string. Without this option, a
* dollar also matches immediately before the final character if
* it is a newline (but not before any other newlines). This option
* is ignored if #G_REGEX_MULTILINE is set.
* @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that
* they are not greedy by default, but become greedy if followed by "?".
* It can also be set by a "(?U)" option setting within the pattern.
* @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this
* flag they are considered as a raw sequence of bytes.
* @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing
* parentheses in the pattern. Any opening parenthesis that is not
* followed by "?" behaves as if it were followed by "?:" but named
* parentheses can still be used for capturing (and they acquire numbers
* in the usual way).
* @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will
* be used many times, then it may be worth the effort to optimize it
* to improve the speed of matches.
* @G_REGEX_FIRSTLINE: Limits an unanchored pattern to match before (or at) the
* first newline. Since: 2.34
* @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not
* be unique. This can be helpful for certain types of pattern when it
* is known that only one instance of the named subpattern can ever be
* matched.
* @G_REGEX_NEWLINE_CR: Usually any newline character or character sequence is
* recognized. If this option is set, the only recognized newline character
* is '\r'.
* @G_REGEX_NEWLINE_LF: Usually any newline character or character sequence is
* recognized. If this option is set, the only recognized newline character
* is '\n'.
* @G_REGEX_NEWLINE_CRLF: Usually any newline character or character sequence is
* recognized. If this option is set, the only recognized newline character
* sequence is '\r\n'.
* @G_REGEX_NEWLINE_ANYCRLF: Usually any newline character or character sequence
* is recognized. If this option is set, the only recognized newline character
* sequences are '\r', '\n', and '\r\n'. Since: 2.34
* @G_REGEX_BSR_ANYCRLF: Usually any newline character or character sequence
* is recognised. If this option is set, then "\R" only recognizes the newline
* characters '\r', '\n' and '\r\n'. Since: 2.34
* @G_REGEX_JAVASCRIPT_COMPAT: Changes behaviour so that it is compatible with
* JavaScript rather than PCRE. Since: 2.34
*
* Flags specifying compile-time options.
*
* Since: 2.14

* @G_REGEX_MATCH_NOTBOL: Specifies that first character of the string is

* only the behaviour of the circumflex metacharacter, it does not

* @G_REGEX_MATCH_NOTEOL: Specifies that the end of the subject string is
* not the end of a line, so the dollar metacharacter should not match
* it nor (except in multiline mode) a newline immediately before it.
* Setting this without #G_REGEX_MULTILINE (at compile time) causes

* the dollar metacharacter, it does not affect "\Z" or "\z".
* @G_REGEX_MATCH_NOTEMPTY: An empty string is not considered to be a valid
* match if this option is set. If there are alternatives in the pattern,
* they are tried. If all the alternatives match the empty string, the

* @G_REGEX_MATCH_NEWLINE_ANY: Overrides the newline definition set when

* U+0085 NEXT LINE (NEL), U+2028 LINE SEPARATOR and
* U+2029 PARAGRAPH SEPARATOR.
* @G_REGEX_MATCH_NEWLINE_ANYCRLF: Overrides the newline definition set when
* creating a new #GRegex; any '\r', '\n', or '\r\n' character sequence
* is recognized as a newline. Since: 2.34
* @G_REGEX_MATCH_BSR_ANYCRLF: Overrides the newline definition for "\R" set when
