[LLVMdev] can't build LLVM under Cygwin | released MinGW llvm-2.3 image

[Chuck Zhao]

I used to be able to build LLVM (from source) under Cygwin for llvm-2.2 
and previous releases, but can't continue the trend since the release of 
LLVM 2.3.
I have tried a wide variety of gcc compilers (gcc 3.4.4, 4.1.2, 4.2.4 
and 4.3.2) on cygwin, they all fail at the same location:

The GettingStarted page mentions that gcc 3.4.4 is used for the 
X86/Cygwin/MinGW build. Is this still true? or there is/are special 
flags/options I am missing?

An other question:
For the published Cygwin/MinGW build, after unzipping, there is just 1 
bin directory. What happens to other related directories (include, lib, 
doc, man, ...) for the 2.3 release build?



Thank you
