Hello list.
I am trying to build llvm, clang, compile-rt and lldb. I am working with
cygwin (don't ask). Here is my tools list.
$ ../llvm-check-tools.sh
make GNU Make 3.80
gcc gcc (GCC) 4.5.3
svn svn, version 1.7.10 (r1485443)
Python 2.7.3
perl Summary of my perl5 (revision 5 version 14 subversion 2) configuration:
m4 m4 (GNU M4) 1.4.16
autoconf autoconf (GNU Autoconf) 2.69
automake automake (GNU automake) 1.12.5
libtool libtool (GNU libtool) 2.4
When I run the following shell script
PATH=/bin:/usr/bin
CC=gcc CXX=g++ ../llvm-3-3/configure --enable-optimized
I get the following warning
checking if /dev/zero is needed for mmap... no
configure: WARNING: mmap() of a fixed address required but not supported
checking for GCC atomic builtins... yes
With this warning, I run the following make script
PATH=/bin:/usr/bin
make CXXFLAGS=-std=c++0x
and I get the following build error.

Any suggestions on what I've done wrong?
