[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

[Aaron Gray]

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.
