[Tux4kids-tuxtype-dev] portable error()?

[Jeremy C. Reed]

src/tuxmathadmin.c uses "error" which is available with glibc and error.h.

This is not on some other platforms.

The following was a quick hack based on some GPL code from vpnc.

Probably the correct way is to detect and include the code conditionally 
as needed.
