[MLton] Cross-Compile

[Brent Fulgham]

Stephen,

I'm trying to cross-compile from Linux to Mingw, but it's failing after
generating the ASM and C files.  I suspect it's looking for the
C compiler, but I don't know  what path it expects to use:
[ ... stuff ... ]
   sxmlPassesSet: <sxmlPassesSet>
   sxmlPasses: [default]
   target: i386-pc-mingw32
   target arch: X86
   target OS: MinGW
   type check: true
   type error: concise
   use basis library: true

[ ... more stuff ... ]

Can you tell me what path it's searching for GCC?  I can't find it by
grepping through the sources.

Thanks,
