      3 Subject: windows vs. llvm
      4 
      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.
