Linking Errors related to X11

[Jack]

The beginning of that (unwrapped)
   g++ -O2 -o aplus.exe /usr/include mainC.o aplus_main.o aplus_uext.o  
matherr.o  -L/usr/local/aplus-fsf-4.22/src/IPC

should probably be
   g++ -O2 -o aplus.exe mainC.o aplus_main.o aplus_uext.o matherr.o   
-I/usr/include  -L/usr/local/aplus-fsf-4.22/src/IPC

/usr/include is a directory to look for includes, not one of the files  
to be compiled
