[LLVMdev] version 1.0, compiling under cygwin

[Valery A.Khamenya]

Hello llvmdev,

  (just for fun) I've tried to compile LLVM under cygwin.
  With "make -k" I got only:

-----------------
DynamicLinker.cpp: In function `void* GetAddressOfSymbol(const char*)':
DynamicLinker.cpp:40: error: `RTLD_DEFAULT' undeclared (first use this 
   function)
DynamicLinker.cpp:40: error: (Each undeclared identifier is reported only once 
   for each function it appears in.)
-----------------
  
well, the only value supported in cygwin's dlfcn.h are RTLD_LAZY,
RTLD_NOW and RTLD_GLOBAL.

So, just for checking compilation I've changed the line

  return dlsym (RTLD_DEFAULT, symbolName);

in DynamicLinker.cpp to the following:

  return dlsym (/*RTLD_DEFAULT*/(void*)RTLD_LAZY, symbolName);

than compilation itself finished, just linkage failed with one screen
output!
The beginning of output is here (sorry if it is too much for this
maillist...) :
