5If you're interested, here are some of the major problems compiling LLVM
6under Cygwin and/or Mingw.
7
81. 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
122. Mingw doesn't have <dlfcn.h> (because Windows doesn't have it.)
13
143. SA_SIGINFO and friends are not around; only signal() seems to work.
15
164. 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
205. There isn't a <values.h>.
21
226. There isn't a mallinfo() (or, at least, it's documented, but it doesn't seem
23   to link).
24
257. 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.
