[llvm-commits] [Cygwin] No runtime lib profile patch

[Aaron Gray]

Hi,

I am getting the following build error on doing a full build on LLVM
on Cygwin :-

I have done a quick patch to omit building of this library for Cygwin
as I am not sure if or how to solve this build on Cygwin.

Index: runtime/Makefile

 install::

Hoping someone more experienced can take a look at this.

Many thanks,

Aaron
