>Description:
When the program includes <fstream> the <prefix>/include/g++-v3/bits/basic_file.h is included before the <prefix>/include/g++-v3/sparc-sun-solaris2.6/bits/basic_file.h, causing the compiler to not to recognise the typedef __c_file. The order of include search seems to be wrong. The text below shows the full output from a simple compile session.

>How-To-Repeat:
Just say:

#include <fstream>

at the top of your source, and try compiling.
>Fix:
Temporary fix:

Renamed the <prefix>/include/g++-v3/bits/basic_file.h to something else (or remove it completely) and the one from the platform include directory will be picked up.
