Summary: Crosscompiling fails with error in src/i386/icsprite.c

Initial Comment:
Hi,

I want to crosscompile Allegro for using it with djgpp under Debian Gnu/Linux. I have a working crosscompiler
($ i386-pc-msdosdjgpp-gcc -v
Using built-in specs.
Target: i386-pc-msdosdjgpp
Configured with: ./configure -v --prefix=/usr --target=i386-pc-msdosdjgpp --disable-nls --host=i686-pc-linux-gnu --enable-languages=c,c++,fortran --enable-version-specific-runtime-libs --with-headers=/usr/i386-pc-msdosdjgpp/include
Thread model: single
gcc version 4.2.2
) and have executed "fix.sh djgpp", patched xmake.sh to use ff. values:

XC_PATH=/usr/local/i386-pc-msdosdjgpp/ XPREFIX=i386-pc-msdosdjgpp- INSTALL_BASE=/usr/local/i386-pc-msdosdjgpp 
..
CPATH=$CPATH:$XC_PATH/include
export CROSSCOMPILE MINGDIR DJDIR NATIVEPATH PATH XPREFIX CPATH

Then the "xmake.sh depend" was processed successfully. But if I try to run "xmake.sh" or "xmake.sh all" there I got the errors:
...
src/i386/icsprite.c: In function 'compile_sprite':

I downloaded allegro as allegro-4.2.2.tar.gz from your Website.

Please could you help me to fix this possible bug?

Since the problem is in ASM blitter code you can try to disable ASM. I'm
not sure how is that done for crosscompiling. I guess you should pass
ALLEGRO_USE_C=1 (x)make.

The problem seem to be at the beginning of src/i386/opcodes.h. Apparently,
gcc #defines __linux__ even when crosscompiling for DOS. You can easily fix
that until a solution is found.
