cdesktop/cde/configure.ac
Jon Trulson 9eee455580 configure: various fixes regarding compiler flags 
First attempt at setting certain -Defines and compiler flags (like
-fno-strict-aliasing).  Only linux for now.

Add CSRG_BASED to CPP_SOURCE_FLAGS rather than directly at CFLAGS.
This will be added to CFLAGS later on in the script along with other
gathered flags and options.

Set CFLAGS, CXXFLAGS, and CPPFLAGS at the end, composed of other env
variables we set earlier on.
