Solution: comp.linux.programmer. This is comp.lang.c where we discuss on
ly the c standard and conforming c code.

..cc is the typical extension for c++ programs which is not covered here.
Try comp.lang.c++.

Sounds like a system-specific pitfall. Try a nesgroup dedicated to your
particular platform/language.

If you have any questions regarding c or the c standard, feel free to

for comp.lang.c.
