compilation issue

Hi friends,
This morning I've updated to current sources and cant compile the
project under mingw.

Compilation fails with:
gcc -I../libavcodec -I../libavformat -Wdisabled-optimization
-Wno-pointer-sign -
Wdeclaration-after-statement -I. -I.. -I../libavutil -Wall -Wno-switch
-Wpointer                                -arith -Wredundant-decls -O4
-march=prescott -mtune=prescott -pipe -ffast-math -
            fomit-frame-pointer -D_LARGEFILE_SOURCE

My backup from 3 days back works but current fails. Later I will
investigate the problem why it fails but now I just want to inform
you.
Currently I see 2 missing headers. But I think configuration procedure
have to detect this and must disable mga.
