[Qemu-devel] qemu on Cygwin

Hi!

 Did anyone try the latest CVS qemu on Cygwin ?

 The build environment adds spacial "-mno-cygwin" option
which among other effects removes defaul *.h path (/usr/include/)
from the search list.

 For example:

-- a.c --
#include <zlib.h>
main () {}
----

$ gcc -c a.c    --- OK

$ gcc -mno-cygwin -c a.c
a.c:1:18: zlib.h: No such file or directory

Default path with -mno-cygwin is /usr/include/mingw,
so zlib.h must be installed there...

You can see the search list with "gcc -mno-cygwin -E -v -".

AFAICT this is due to SDL. I did not succeed in compiling any SDL related 
stuff in cygwin, but then, I did not really try, since the MinGW 
compilation is easy enough. (Also, the executables are slightly faster, 
since they don't have to emulate a POSIX layer on top of the Windows 
crAPI.)

 I've successfully compiled SDL 1.2.11 on the fresh-installed Cygwin 1.5.24.
The following test SDL application works:
http://www.cse.nd.edu/courses/cse20211/www/code/sdl.html

 The SDL/test contains a bunch of SDL testing applications.
Most of them works too, even sound- and OpenGL related.

sdl-config adds -mno-cygwin option so that SDL on Cygwin uses MinGW
compiler.
An attached patch makes compile on Cygwin. But I have to downgrade
mingw-runtime from 3.11 to 3.10.
