OpenBSD 3.5 doesn't define INT8_MIN, INT8_MAX, UINT8_MAX etc. OpenBSD
only defines INT_MAX, UINT_MAX, SIZE_MAX, SSIZE_MAX etc. I could write
a patch for gen-scmconfig.c and/or configure.in that handles this
problem but I'm wondering why INT8_MIN etc. are necessary at all. Are
there any architectures where INT8_MIN, INT16_MIN etc. aren't -128,
-32768 etc.?
