Subject: Use #ifdef instead of #if in gvloadimage_core.c
X-Git-Tag: 2.42.0~189^2~9
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2105b84e8c2ffa25458d0e5430f9862fffa13230;p=graphviz

Use #ifdef instead of #if in gvloadimage_core.c

Replace `#if HAVE_SYS_MMAN_H` with `#ifdef HAVE_SYS_MMAN_H`. Using the
former causes problems is HAVE_SYS_MMAN_H is defined without a value.
