   5 If you're interested, here are some of the major problems compiling LLVM
   6 under Cygwin and/or Mingw.
   7
   8 1. Cygwin doesn't have <inttypes.h> or <stdint.h>, so all the INT*_MAX
   9    symbols and standard int*_t types are off in limbo somewhere. Mingw has
  10    <stdint.h>, but Cygwin doesn't like it.
  11
  12 2. Mingw doesn't have <dlfcn.h> (because Windows doesn't have it.)
  13
  14 3. SA_SIGINFO and friends are not around; only signal() seems to work.
  15
  16 4. Relink, aka ld -r, doesn't work (probably an ld bug); you need
  17    DONT_BUILD_RELINKED. This breaks all the tools makefiles; you just need to
  18    change them to have .a's.
  19
  20 5. There isn't a <values.h>.
  21
  22 6. There isn't a mallinfo() (or, at least, it's documented, but it doesn't seem
  23    to link).
  24
  25 7. The version of Bison that cygwin (and newer Linux versions) comes with
  26    does not like = signs in rules. Burg's gram.yc source file uses them. I think
  27    you can just take them out.
