[Cygwin] Cygwin 'make check' failures

I have attached the Cygwin ‘make check’ results, and am hoping that someone can enligten me as to some of the results.

For example :-

FAIL: /home/ang/svn/llvm/test/ExecutionEngine/test-call.ll
Failed with signal(SIGABRT) at line 2
while running: lli test-call.ll.tmp.bc > /dev/null
assertion “Inserted && “Pass registered multiple times!”” failed: file “/home/ang/svn/llvm/lib/VMCore/Pass.cpp”, line 149

There are multiple tests failing on this same problem. Why is this failing just on Cygwin. It seems strange ?

There are lots of X86-64 tests failing in the same place also :-

FAIL: /home/ang/svn/llvm/test/CodeGen/X86/stride-nine-with-base-reg.ll
Failed with signal(SIGABRT) at line 2
while running: llvm-as < /home/ang/svn/llvm/test/CodeGen/X86/stride-nine-with-base-reg.ll | llc -march=x86-64 | not /usr/bin/grep lea
assertion “!TM.getSubtarget().is64Bit() && “X86-64 PIC uses RIP relative addressing”” failed: file /home/ang/svn/llvm/lib/Target/X86/X86InstrInfo.cpp", line 3192

Many thanks in advance,

Aaron
