[PATCH] Check if DEBUG is defined in regex_internal.h

[Siddhesh Poyarekar]

Hi,

The DEBUG macro is checked for its value in one place and if it is
defined in another.  Make this consistent across the two cases and use
the same style that we did in mktime.c, which is to check if the macro
is defined and it is set.

Siddhesh

	* posix/regex_internal.c: Check if DEBUG is defined and is
	set.
