One easy way is to use a wrapper program.
Create a small shell script called gcc, make sure it is in a
directory that is earlier in your $PATH than any other gcc.
case "`uname -m`" in
sparc64) CPU="ultrasparc" ;;
amd64) CPU="athlon64" ;;
/usr/pkg/gcc34/bin/gcc -O2 -mcpu=$CPU $@
This also provides an easy way to add extra warnings to help
catch code that assumes ILP32 such as -Wmissing-declarations
-Wmissing-prototypes -Wstrict-prototypes and so on.
You can have cc use the same compiler by creating a symlink.
This way you *always* get your desired compiler and compiler flags,
even when you compile a small test program with "gcc mytest.c"
and don't have a Makefile that handles CFLAGS and such.
