Hi Ted,

*no* program will be "portable" and usefull in 8 years
(TeX perhaps, but not with out the TeX comunity)
if the developer dont't continue it's development.

Even MathLink has got some remarkable changes (strings
characters, unicode) in the last years. 

But you are rigth. The well accepted ANSI standard is
a strong plus to vote for C.

But for C++ the situation is different, the standard
is only tow or three years old and the usage of
C++ stuff like templates cause trouble even when you
switch to a different compiler on the same machine.

For the next years, the prospects are even worse. 
Because PC's will get a 64 bit CPU and this may cause
several troubles if the program is not well designed.
The size of int, short, long is still a great source
of unexpected results in an ANSI-C program.

Regards
  Jens
