+ * 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.
