Hi,

I'm the maintainer of a windows hosted arm-elf gcc toolchain used mostly
for homebrew console development. One of my users recently asked if I
could have a look a getting elf2flt to build under mingw/msys to help
with his uclinux Nintendo DS port. I've attached a patch containing the
changes I made to the source in CVS, thought it might be useful.

2005-09-25  Dave Murphy  <davem@devkitpro.org>
   * Makefile.in: add ws2_32 library when building from msys shell.
   * cygwin-elf.h: On mingw.include stdint.h and add extra typedefs
   * elf2flt.c: Include cygwin-elf.h on mingw too.
   * flthdr.c: For mingw use winsock2.h for internet consts & structs ,
     use mktemp instead of mkstemp

Dave
