I don't understand this: C_INCLUDE_PATH is set, DJGPP is also set, and
yet the MGL include directories don't appear on the search path
reported by the compiler:

How can this be??  Did you edit DJGPP.ENV?  It should have a fragment
like this:

[cpp]
CPLUS_INCLUDE_PATH=%/>;CPLUS_INCLUDE_PATH%%DJDIR%/lang/cxx;%DJDIR%/include;%DJDIR%/contrib/grx20/include
C_INCLUDE_PATH=%/>;C_INCLUDE_PATH%%DJDIR%/include;%DJDIR%/contrib/grx20/include

Do you have it, or is it somehow changed?  It is especially important
that the first part after the equals sign `=', the one which mentions
C_INCLUDE_PATH, is present, since that's what makes the value of
C_INCLUDE_PATH, as you set it in the environment, be prepended to the
defeault directories.  Please make sure that this line is intact.

Does anyone know how could the compiler ignore C_INCLUDE_PATH?

What do you need this variable for?
