Hi, 
I downloaded the MESA-3.0 package, hoping to use it to accelerate my DJGPP 
code on cards that support the openGL functions. I've seen a lot of messages 
here that have given me the idea it is impossable to do that with DJGPP in 
dos.

However, the Mesa package comes with DJ makefiles, so that tells me it can be 
done.  I tried to compile the mesa libs, but got a lot of errors such as 
these:

make.exe[1]: Entering directory `c:/Prog/djgpp/Mesa-3.0/src'
gcc -c -DDOSVGA -I../include -O3 -m486 dosmesa.c
dosmesa.c: In function `DOSmesa_setup_DD_pointers':
dosmesa.c:1311: warning: assignment from incompatible pointer type
dosmesa.c:1326: structure has no member named `WriteColorSpan'
dosmesa.c:1327: structure has no member named `WriteMonocolorSpan'
dosmesa.c:1328: structure has no member named `WriteColorPixels'
dosmesa.c:1329: structure has no member named `WriteMonocolorPixels'

Has anyone compiled this on DJ 2 , gcc 2.8.1 ?  The errors mean, to me, that 
either this  DJGPP or Mesa version is incompatible with the other.
