Hi Guix,

I've cleaned up my gctp patch, following your advice:

I took the contents of the gctpc20.tar.Z archive distributed with 
wgrib2, added an autoconf-based build script, and published the 
repository on Github.  Changes are minor: I had to make some changes 
to the test programs, and fix one input routine (int size mismatch 
when reading an auxiliary binary file).

This version of the patch uses a release tarball published on github. 
 Is there a better place I can host a tarball (if not the repository 
itself?).

best,

Thomas
