X-Git-Tag: gc7_3alpha2~189
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dce915e3ee6b408049f905b917af7711d388c08c;p=gc

Recognize GC_LOG_TO_FILE_ALWAYS macro to log to 'gc.log' by default

* misc.c (GC_init): If "GC_LOG_FILE" environment variable is unset and
GC_LOG_TO_FILE_ALWAYS macro defined then open "gc.log" file for GC
logging (only Unix and Cygwin).
