[MLton-commit] r4141

[Stephen Weeks]

Used #ifndef to protect some #defines.  This is necessary on some
platforms, like Solaris 10, that define fpclassify and associated
constants, but where we say that HAS_FPCLASSIFY = FALSE (because
Solaris 8 doesn't have fpclassify).

We really should use autoconf.
