Because this might be a question of general interested I answer it
on the list. :)

Porting C programs to GNU/Linux is mostly easy.
GNU/Linux and most other unix have standard ANSI-C compilers and conform
mostly to the POSIX system standard. The only thing you have to port is
if you use system specifc libaries or system calls.

If your program just deals with reading, translating and writing text
or binary formats it should be portable right away. Two pitfalls are the
different line endings in text format and the binary option for reading
and writing binary files. You also make sure the endianess is conserved
for all cases.

I would appreciate if you put it unter a free software license
and make it available online somewhere. If you think GPL is too strong
for your small tool, you can consider LGPL or the MIT style license.

Thanks,
