[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

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.

[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

Okay I have put a #ifdef HAVE_RLIMIT_RSS round the RSS code.

There needs to be logic added to config system to complement this.

Or shall I just use an #ifdef _CYGWIN_ ?

Regarding the Bytecode writer stuff. I will try adding some inline 
dis-ambiguator functions.

Yeah, I can't help you solve this problem because I don't have your
environment or compiler. However, this really smells like a compiler or
stdint.h bug to me. This code compiles fine on many unix platforms and
also under mingw.
