#31 THE files getch.c and getch.h have a license incompatible with GPL.

[Mark Post]

We are trying to package The Hessling Editor for the openSUSE Package Hub, but we've encountered a problem with the licensing. The source code includes two files, getch.c and getch.h, that have a non-GPL compatible license on them. Specifically:
Permission is hereby granted to copy, distribute or otherwise
use any part of this package as long as you do not try to make
money from it or pretend that you wrote it. This copyright
notice must be maintained in any copy made.

Is there any way those files can be replaced with code that has a GPL compatible license?
