Turning Off Compiler Optimization in Subdir

[Geoffrey Hutchison]

Hi,

OK, my automake-driven project has managed to find a C++ compiler bug  
due to optimization. Fortunately, the problem is only in a few files  
in a subdir.

What I'd like to ensure is that compiler optimization is *not* used  
by default for this subdirectory. But if I set AM_CXXFLAGS (e.g. to "- 
g -O0"), the default configure flags (-g -O2) override.

While I could set the default configure CXXFLAGS to just "-g -O0" and  
use AM_CXXFLAGS in every other Makefile.am to add optimization for  
those source files. But this seems like a hack (changing everything  
else to modify one subdir). Is there another way, preferably only  
modifying the Makefile.am in the affected subdir?

Thanks very much in advance!
