Mike,
I tried with IBM's XLC 13.1.2 and these options were ignored: -Wall -Wpedantic -Wformat=2 -Wconversion -Wno-long-long -Wno-depreciated-declarations
I compiled it as follows: cd ~/SRC; rm -rf stunnel-5.27; gzip -dc stunnel-5.27b3.tar.gz | tar xvf -; cd stunnel-5.27 export CFLAGS="-qstackprotect=size=0" ./configure --enable-fips --disable-ipv6 --with-threads=pthread --with-ssl=/usr make
I didn't have to use "gxlc" (IBM's "gcc clone"), and other than the warnings for the unrecognized parameters above, it seems to work. I added the extra CFLAGS parameter to ensure stack smashing protection is enabled (disabled by default on XLC).
I can see how it would be nearly impossible to maintain compatibility with compilers from different architectures and different versions with different arguments. Thanks for the patch!
Regards, -Rob

I think this is a good idea. Other projects deal with the issue in a similar way. On Oracle Studio the compiler flags are basically ignored and issue a warning but produce a working binary, but the build process is cluttered with warnings. Even when you fix the macros this issue would stay, so restricting the checks to gcc is probably the best way.
