These are the binaries you need to be able to compile the neuron program. These files were copied from oak.oakland.edu:pub/msdos/djgpp. Sources are also available at this and other SimTel sites. Read the readme.1st file. Copy the djg/contrib/bcc2grx/lib/libbcc.a and djg/contrib/libgrx/lib/libgrx.a files to the djg/lib directory so you can do Borland compatible graphics.
