Three Issues with Building LLVM/CFE Under Cygwin

Hello

  I just successfully built, but not yet tested LLVM/CFE, revision 103915, under Cygwin/XP. This email reports three issues, one, possibly, in need of repair and two, for the record, so that fellow suffers may solve similar problems more quickly. Let me know if you would prefer not to clutter the cfe-dev list with the latter sorts of message.

=====[ISSUE #1]==========================================================================
Possible Problem with AC_LINK_EXPORT_DYNAMIC m4 macro in LLVM/autoconf/m4/link_options.m4
