Was that intended as a new flag for 1.8.0?
The intended flag was -std=c90, yes. You should be able to use just plain CFLAGS= instead of EXTRA_CPPFLAGS=, the problem with initial CFLAGS being overriden should have been fixed. > The flag is set by SVN_CC_MODE_SETUP in build/ac-macros/compiler.m4 and > passes along into CMODEFLAGS in the Makefile.

Could you provide a patch that does that? I expect the best place would be in the SVN_CC_MODE_SETUP macro in compiler.m4. -- Brane -- Branko Čibej | Director of Subversion WANdisco // Non-Stop Data e. br...@wandisco.com
