[LLVMdev] Building LLVM on Windows

[Gordon Henriksen]

Hi Alain,

Thanks for all this! I'll restrict my comments to the ocaml bindings…

Can you explain the cause of this behavior? CFLAGS += appears in  
Makefile.ocaml after include …/Makefile.config to avoid precisely this  
problem.

I don't have a Cygwin environment to test in. Please apply the  
attached configure.patch to see if it's suitable (autoconf.patch is  
the source). If it works well, I'll commit it.

Done.

Looks like you set SYSPATH by hand? I'll hold off on this for now.

I guess we need a configure test?
