I can't compile mesa under DOS with DJGPP either with GCC 2.8.1 or
PGCC 2.90. The first problem encountered is when compiling \src,
'make' can't find 'depend.dos', which I worked around it by adding
'\dos' to 'include depend.dos' line. Is it right to do so? 'cause I
found 'depend.dos' in \src\dos.
The second problem which I can't seem to understand that GCC/PGCC
can't find 'GL/gl.h'. I have checked '\include' and found the file
there but why does the compiler can't found it? I even give absolute
addresses to 'INCLUDE' and 'LIB' variable but nothing improved. How
to work around this problem?
