 * 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)

 *
 * 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.
 *
