Subject: [GCC4] fix build error in drivers/sound/wavfront.c

This patch fixes this error with gcc 4 :

wavfront.c:2490: error: static declaration of 'errno' follows non-static declaration
/usr/src/git/linux-2.4/include/linux/unistd.h:4: error: previous declaration of 'errno' was here

The solution is to workaround errno the same way as in sound_firmware :
