Hi Aaron,

Most of these look like general non-portability of LLVM 2.0 to  
cygwin, either of tests or of specific features.

Please file a bug with this information in it, and hopefully someone  
will improve it for 2.1.  Most of the issues appear to be things we  
don't claim to support:

1. CFrontend/extern-weak.c is just not portable to cygwin yet.
2. The debugging tests don't work on cygwin, because apparently debug  
info doesn't work there yet.
3. There are some portability issues with alloca, as you noticed.
4. There is a small smattering of real bugs, such as llc targeting  
cygwin/x86-64.  We don't support this target yet, but should fix the  
bugs as we find them.

Thank you for testing this.  Despite a few non-portability issues in  
the testsuite and a few unsupported features, it looks like cygwin is  
in pretty good shape!
