Cygwin is broken twice now. I reported this on the commits list and submitted a patch, but no one has checked it out as of yet.

FWIW, I applied your patch for the OTHER Cygwin failure yesterday, so that one should be fixed.

Owen,

Great thanks, the patch was okay then.

This latest break looks like its probably a binutils version problem, a newer feature being used '--enable-runtime-pseudo-relocs' for 'libCompilerDriver.dll'. Cygwin uses ld 2.18.50.20080625, this is the latest availiable for Cygwin.

Interesting.
Does libCompilerDriver.dll link w/o '--enable-runtime-pseudo-relocs'?

If I understand correctly, this bug makes it impossible to produce loadable
modules on Cygwin.

I have not tried as of yet.

I don't think Cygwin supports loadable modules anyway.

How do I disable this just on Cygwin ?

Just compile with `make VERBOSE=1` and then copy, paste & edit
the offending line.

Really, Cygwin doesn't allow to produce DLLs? Then I guess I
should make this a configure option.

I sent you a _patch_ that disables it on Cygwin for the time being. LLVM does not load DLL's properly apparently. I would love to get to the bottom of this at some point.

Anyway the patch is on the commits list anyway.

I've just added an --enable-llvmc-dynamic configure option (enabled
only on Windows by default). This is based on your patch.
