[distcc] Patch to make distcc mingw-friendly

[Alex Besogonov]

Here is a small patch that makes distcc mingw-friendly:
http://elewise.com/~cyberax/mindistcc.zip

Currently, distcc doesn't work with mingw because it creates temporary
files in '/tmp/' or '/cygdrive/<TMPDIR>' directory. These are NOT valid
win32 paths which mingw expects.

PS: Thanks for this great tool!
