The following is a completely untested idea, but the idea seems sound.
You'll need to use the flag that will make the compiler print out its
version info, which I'll call '-v' in my code example below
if test x$GCC = "x"; then
mips_pro=`cc -v | grep MIPSPro`
if test x$mips_pro != "x"; then
CXXFLAGS="${CFLAGS} -LANG:std"
fi
fi
The 'MIPSPro' in the grep command should be a unique string in the
compiler version printout that is unlikely to appear in another
compiler. As this is just shell scripting, there are additional
types of tests that can be done, such as calling uname to test
the OS type.
