[Gluster-devel] [PATCH 06/15] build: consolidate common compilation flags into one variable

Jan Engelhardt jengelh at inai.de
Tue Sep 25 16:41:04 UTC 2012 

Some -D flags are present in all files, so collect them.
This adds -D${GF_HOST_OS} to some compiler command lines,
but this should not be a problem.
