## #3737 — Vesselin Atanasov — 2003-08-05T20:18:30+00:00

Hello.
In regex/utils.h there is a definition for DUPMAX:

#ifdef _POSIX2_RE_DUP_MAX
#define	DUPMAX	_POSIX2_RE_DUP_MAX
#else
#define	DUPMAX	255
#endif

On Linux with glibc this effectively sets the DUPMAX count to 255. But I
think that this
number is too low, so there is no way to use a regex like .{1,256}
Is there any chance that this number will be increased or at least made
configurable?
I can make a patch if the maintainer is interested.
