convertlit fixes - thanks!

[Richard L. Hamilton]

Thanks, I appreciate the quick fixes!

Did those get passed upstream? Seems to me that they should be quite portable, insofar as one should always use the appropriate include files with library routines, and the lzx.h header file should have had those declarations in it anyway.  Maybe Macs are seeing this before most others, but I imagine sooner or later, compilers everywhere will get ever pickier about such things.

If I'm looking in the right place, the contact is drs at convertlit.com The last update on the website looks old (2004!) so I have no idea whether the email works or would be read.
