[LLVMdev] gfortran link failure in current llvm svn

The curent llvm svn (r54623) is unable to link the gfortran
compiler in llvm-gcc-4.2 svn. I am getting the error...

this is probably due to recent Apple changes.  Fortran builds on
linux.

I think this is because some people may not have C++ in the list
of languages to build.  There's even a PR about this:
http://llvm.org/bugs/show_bug.cgi?id=1150

Ciao,

Duncan.

Duncan,
   I don't be that can be the cause because I have...

--enable-languages=c,c++,fortran

in my configure options for llvm-gcc-4.2.

It's just horrendous. For some reason, they placed a whole bunch of  
ObjC-building code into darwin.c, then had it call this function in  
darwin-c.c. If I try to put that function into darwin.c, all hell  
breaks loose. So even though the Fortran stuff wouldn't call the Obj-C  
stuff in darwin.c, it appears like it still needs the darwin-c.c file  
linked in with it.

Jack,

Could you try this patch to see if it works for you?
