I'm using

   djdev203.zip
   gcc2952b.zip
   grx23.zip
   grx23fnt.zip
   grx23.update.000520.gz

I can build the library without errors, but I get the following error when I
try to build the /test directory:

=== ERROR TEXT ===
C:\DJGPP\grx231\test>make -f makefile.dj2

The output from an "nm" on "libgrx20.a" gives

=== NM OUTPUT ===

Notice the _GrLine is type "U", or undefined.  If I do an "nm" on the line.o
file, the symbol _GrLine is type "T", or code.  Something is getting lost in
the link, but I don't know why.
