Hello!


I'm working on completing the Win32-port of the 20010806
release of MLton now. I have now come to the point where
the compilation complains about compiling mllex - so I think
MLton itself compiles now (but that probably far from means
that it works of course - most of the code I messed with is
C-code after all ;)

Anyways - I have attached gc.c from the runtime. I would like
you guys to review / fix the code if you know of any potential
problems. And all changes should only apply if the _WIN32 flag
is defined - so I hope it's still equivalent to gc.c in
version 20010806 on Linux at least.

In particular I'm concerned about the following:

1) I commented out a lot of timing stuff - which doesn't exist
   on Win32, but it seems mostly to be for debugging and feedback
   so I hope it's not important (we only cross-compile applications
   to Windows which already work on Linux - right? :)
2) It seems the garbage collector doesn't do memory shrinking of
   the stack anymore (the ML call-stack i presume?) as it did
   in the old version I ported. This should actually give one
   problem _less_ on Win32 - but maybe the code has just changed
   and maybe you still do stack shrinking, only in a different way?
3) There are no signals in Win32 - I'm not sure if it's safe to
   just uncomment all that stuff (after all the GC seems to
   only be concerned about disabling those signals... :)
   and if I've done it right.
4) Win32 does not have the mprotect function - so I uncommented
   that in ssmmap - but ssmmap is not even called anymore - after
   the uncommenting of everything in the function initSignalStack 
   because of the signals (which I'm not sure will be safe either?)
   So maybe ssmmap is not important at all...

Anyways - look for the following in the code:

_WIN32
FIXME:
DONT_SHRINK_MEM
DONT_USE_SIGNALS

I hope you can give some feedback :)


Cheers
