[Qemu-devel] Compiling qemu with nas installed

[Hasso Tepper <hasso@estpak.ee>]

If user has packages installed in "nonstandard" paths (like pkgsrc package 
system used by NetBSD and DragonFly - /usr/pkg), CPPFLAGS and LDFLAGS are 
used normally by users to help configure scripts etc to find headers and 
libraries.

$ export CPPFLAGS=-I/usr/pkg/include
$ export LDFLAGS=-L/usr/pkg/lib

This causes the problem if user has the nas software package installed:

  CC    wm8750.o
/tmp/q/wm8750.c:24: error: expected specifier-qualifier-list 
before 'QEMUSoundCard'
/tmp/q/hw/wm8750.c: In function 'wm8750_in_load':
/tmp/q/hw/wm8750.c:59: error: 'struct wm8750_s' has no member 
named 'idx_in'
/tmp/q/hw/wm8750.c:59: error: 'struct wm8750_s' has no member 
named 'req_in'
etc etc etc

The problem comes from fact that the nas package has also audio/audio.h 
file and it's included in wm8750.c if user or package system defines 
CPPFLAGS which happen to include the path to the audio/audio.h from nas. 

I don't how to fix it correctly, but I think that local paths should be 
always before system or user specified ones.
