I'm not talking about reverting Mark's patch.  We need to keep the
positive effects of that while restoring the old behavior wherein it
avoided these gratuitous header file transformations on solaris.

That means in inclhack.def, we need to bypass the "hacknames"
"strict_ansi_not", "strict_ansi_not_ctd" and "strict_ansi_only" when
"mach" equals "*-*-solaris2*".
