* | * generic/regc_cvec.c (addmcce):Miguel Sofer2006-09-271-0/+5
| | | | | | | | | | | | | | | | * generic/regcomp.c (compile): the static function addmcce does nothing when called with two NULL pointers; the only call is by compile with two NULL pointers (regcomp.c #includes regc_cvec.c). The whole thing is now ifdef'ed out with the macro REGEXP_ADDMCCE_UNUSED. This also silences coverity's #7.
