error while building gcc 2.95.2 by gcc 3.2

[Chao Liu]

Hi,

While I am now working on the comparison between gcc 2.95.2 and
gcc 3.2 through the testsuite shipped with gcc 3.0.2, I have some
problems with gcc 2.95.2's installation.

The error messages in building gcc 2.95.2 are as follows:

../../../gcc-2.95.2/libio/indstream.cc: In method `struct streampos 
indirectbuf::seekoff(long long int, ios::seek_dir, int = 3)':

`int'was expected

This is an incompatibility between glibc and libstdc++.  It is fixed
in gcc 2.95.3.  If you want to build with a newer version of glibc,
you need to use 2.95.3 instead of 2.95.2.
