[LLVMdev] install question

[Rubin, Norman]

I'm trying to install llvm on my windows development box and hit a
problem
I'm using cygwin 
cygwin% gcc --version
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

I downloaded both the top of tree via svn
I ran ./configure 
      make

make[1]: Entering directory `/cygdrive/c/llvm/lib/Support'
llvm[1]: Compiling APFloat.cpp for Debug build 
llvm[1]: Compiling APInt.cpp for Debug build 
APInt.cpp: In member function `void
llvm::APInt::Profile(llvm::FoldingSetNodeID&) const':

cygwin%

I also tried the 2.3 release and got the same error. 
I must have done something wrong - some care to enlighten me?  
Hopefully this has not been asked many times already.  If it is well
known, where should I have looked for the answer?
