Fixed bug 948

Simon Howard 2010-02-13 13:57:20 PST

Created an attachment (id=490) [details]
Patch against SDL_mixer 1.2.11 to add MingW32CE support.

Following bug 947, this is a patch against SDL 1.2.11 to make SDL_mixer build
with MingW32CE.

Some notes:

1. Native MIDI is disabled because it is not present on Windows CE
2. I added header/function checks for signal() and setbuf(), which do not exist
on Windows CE.
3. Uses of getenv() have been replaced with SDL_getenv().
4. version.rc is not included in the build, for the same libtool-related
reasons as in the previous bug.
