[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

This was just recently added. Does cygwin even have getrlimit and
setrlimit?  IIRC correctly, it doesn't. So, perhaps these functions need
to be written differently for Cygwin. What's the equivalent win32 call?

If cygwin does have getrlimit/setrlimit then we'll have to figure out
what RLIMIT_RSS should be under cygwin. Is there the notion of running
set size under cygwin?

[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

Hi Reid,

Cygwin 'sys/resource.h' has get/setrlimit() functions support for 
RLIMIT_DATA and RLIMIT_AS but not RLIMIT_RSS.

Then, please fix it to not use RLIMIT_RSS in the cygwin case. Perhaps
you should just use RLIMIT_AS for cygwin. It will trigger sooner than
RLIMIT_RSS but that's probably okay.
