- * Prototypes etc. marked with "^" within comments get gathered up (and
- * possibly edited) by the regfwd program and inserted near the bottom of this
- * file.
- *
- * We offer the option of declaring one wide-character version of the RE
- * functions as well as the char versions. To do that, define __REG_WIDE_T to
- * the type of wide characters (unfortunately, there is no consensus that
- * wchar_t is suitable) and __REG_WIDE_COMPILE and __REG_WIDE_EXEC to the
- * names to be used for the compile and execute functions (suggestion:
- * re_Xcomp and re_Xexec, where X is a letter suggestive of the wide type,
- * e.g. re_ucomp and re_uexec for Unicode). For cranky old compilers, it may
- * be necessary to do something like:
- * #define	__REG_WIDE_COMPILE(a,b,c,d)	re_Xcomp(a,b,c,d)
- * #define	__REG_WIDE_EXEC(a,b,c,d,e,f,g)	re_Xexec(a,b,c,d,e,f,g)
- * rather than just #defining the names as parameterless macros.
- *
- * For some specialized purposes, it may be desirable to suppress the
- * declarations of the "front end" functions, regcomp() and regexec(), or of
- * the char versions of the compile and execute functions. To suppress the
- * front-end functions, define __REG_NOFRONT. To suppress the char versions,
- * define __REG_NOCHAR.
- *
- * The right place to do those defines (and some others you may want, see
- * below) would be <sys/types.h>. If you don't have control of that file, the
- * right place to add your own defines to this file is marked below. This is
- * normally done automatically, by the makefile and regmkhdr, based on the
- * contents of regcustom.h.
