Problems with modern C compilers

[sth0]

Code from old website does not compile on modern C compilers. All the function definitions need the types specified in the top line. I have a huge patch file that does this and compiles the code under MacOSX as part of a fink package manager. Will this code ever be updated to handle modern (ie C99 and later) versions?

I have equipment where the YMODEM protocol is needed and this has been a workhorse for me.
