As I mentioned, it looks like llvm-gcc is installed properly. From

LLVMGCC  := /usr/local/bin/llvm-gcc.exe
LLVMGXX  := /usr/local/bin/llvm-g++.exe
LLVMCC1  := /usr/local/libexec/gcc/i686-pc-cygwin/4.2.1/cc1.exe
LLVMCC1PLUS := /usr/local/libexec/gcc/i686-pc-cygwin/4.2.1/cc1plus.exe

It looks to me that this:

make[4]: *** No rule to make target `Output/sse.expandfft.linked.rbc',
needed by `Output/sse.expandfft.linked.bc'.  Stop.

means that make is trying to build this (from Makefile.programs):

# Given an unoptimized bytecode file that is a simple linkage of all
# the program's bytecode files, optimize the program using the
# standard compilation optimizations.
$(PROGRAMS_TO_TEST:%=Output/%.linked.bc): \
Output/%.linked.bc: Output/%.linked.rbc $(LOPT)
        $(VERB) $(RM) -f $(CURDIR)/$@.info
        -$(LOPT) -std-compile-opts -info-output-file=$(CURDIR)/$@.info
$(STATS) $(EXTRA_LOPT_OPTIONS) $< -o $@ -f

But for some strange reason it can't find this rule (from Makefile.singlesrc):

Output/%.linked.rbc: Output/%.bc
        -cp -f $< $@

What can be a reason for this?
