Preprocessed source stored into /tmp/ccTpy3rO.out file, please attach this to your bugreport.
make: *** [intparam.h] Error 1

I tracked this down to the following two calls:
test_integer_casts(schar,longlong,"char","long long",char_bitsize,longlong_bitsize,2);
test_integer_casts(schar,ulonglong,"char","unsigned long long",char_bitsize,ulonglong_bitsize,2);

Commenting both lines out allowed the build to continue, but of course I'm not sure if there's still a bug around, either related to the platform, the compiler or clisp.
