GCC only needs to know this type for the purposes of defining limits for stdint.h. Unless your signal.h does typedef __SIG_ATOMIC_TYPE__ sig_atomic_t; this should only affect the testcases gcc.dg/c99-stdint-[56].c, not actual user code. And as you have discovered, there are rules for these type strings documented in tm.texi under SIZE_TYPE; to use some other variant you'll need to find and eliminate all the dependencies on whatever rule you wish to change. Logically these macros should be hooks returning enumeration values from a defined set of possible types, not strings at all. See past discussions with Joern, e.g. <http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02900.html> and <http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00964.html>. -- Joseph S.
