Subject: Do not compile backgraph.c unless configure '--enable-gc-debug'
X-Git-Tag: gc7_3alpha2~26
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=92bd2e3d95d6dcab9ffd2dc5db92970f8fcb066c;p=gc

Do not compile backgraph.c unless configure '--enable-gc-debug'

* Makefile.am (libgc_la_SOURCES): Exclude "backgraph" entry from
unconditional list; add this entry only if MAKE_BACK_GRAPH.
* configure.ac (MAKE_BACK_GRAPH): New AM conditional (defined only if
enable_gc_debug explicitly set to yes).
