Don't bother with mico.  It is a _heavy_ compiling and newer versions
of Gnome have abandonned it.

About the C problem: Rdhat 5.1 uses gcc 2.7 when compiling C and egcs
(equivalent to gcc 2.8) when compiling C++

You can use gcc 2.8 for C if you want becuase this should not create
problems, however the problem is C++.  gcc 2.8 uses a different
library: that meant that we should have versions for RedHat 5.0 people
and different versions for RedHat 5.1 and later.  There are problems
enough with libc, against glibc.

Another solution could be to provide the 2.8 C++ library to 5.0 and
4.2 users and then go ahead and rebuild the C++ packages we have.

What do think you about it?

Ah! could you put somewhere where I could grasp them the SPEC files of
the packages you fixed.  It is your implementation and not mine who
should be used in the future.
