Phil,

Here is a snip from notes I kept when porting some stuff to DJGPP:

<snip>
Also, even though the GNU make program accepts long command within
makefiles, this does not mean that make itself can be invoked with a
long command line. In particular, if GNU make is spawned from
a typical PC C++ compiled program, the command line gets chopped
to 126 characters, whereas the PC make program (nmake, smake, Borland make)
do not. The only work-around is to compile the program
from which the spawn call to GNU make is made with g++.
<end-snip>
