This is fascinating. In a matter of one week gpasm has appeared on two new OS's.

For a patch this small, the information you provide is sufficient. If you
intend to perform major surgery on gpasm (or whatever), then I'd recommend doing
something like this:
1) create the original source (and don't touch it!)
2) make a copy of the original source
3) edit your copy
4) compare the differences and send the patch
These first two steps could be done like this:
$ mkdir ~/gnupic
$ cp gpasm-0.9.2.tar.gz ~/gnupic/.
$ cd ~/gnupic
$ tar -xzf gpasm-0.9.2.tar.gz
$ cp -r gpasm-0.9.2 my_gpasm
This will unpackage gpasm into a directory ~/gnupic/gpasm-0.9.2 and create a
copy in the directory ~/gnupic/my_gpasm (the ~/ is an abbreviation for your home
directory, e.g. try this: ls ~ ).
Now you can edit the files in your copy of gpasm. When it's time to send a patch
do this
$ cd ~/gnupic/my_gpasm
$ make distclean
$ cd ~/gnupic
$ diff -ur gpasm-0.9.2 my_gpasm > mypatches_for_gpasm.0.9.2.patch
The 'make distclean' will get rid of object files and etc. that can make the
diff contain a bunch of garbage. The program `diff' will perform the difference.
The option `u' means to perform a unified diff. This just makes it easier to
read the diff files. The option `r' means to recursively compare the copies.
This will work. However, in some instances you may need to clean your working
copy more than `make distclean' will. If that's the case, you may wish to do
this:
$ cd ~/gnupic/my_gpasm
$ make dist
(this will create a gpasm-0.9.2.tar.gz file)
$ tar -xzf gpasm-0.9.2.tar.gz
(this will expand the newly created tar ball into a 'pristine' set of files with
your changes)
$ mv gpasm-0.9.2 ../gpasm-0.9.2.my_changes
$ cd ..
$ diff -ur gpasm-0.9.2 gpasm-0.9.2.my_changes > mypatches_for_gpasm.0.9.2.patch
I'm sure others will have some comments about this, but this should work for
you.

PS. Has anyone seen the new gpasm web page that Craig has created:
