Subject: Silence some -Wunused-but-set-variable warnings
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0c517679c48753d0290621f04679c24755e1d346;p=nethack

Silence some -Wunused-but-set-variable warnings

If NH_DEVEL_STATUS was set to NH_STATUS_RELEASED or NetHack was compiled
without DEBUG defined, the 'vlen' variable in a couple pline.c functions
wasn't used.  This could trigger compiler warnings.
