>Organization:
>Environment:
Linux 2.4.18 Glibc 2.2.5
>Description:
Weak alias seems to be rejected where they
were formerly accepted by gcc 3.1.
This prevents compiling glibc 2.2.5
(this PR is a duplicate of 7431, but
the given file was not preprocessed and
I wanted to give a preprocessed one.
Feel free to bind these PRs together),
and hence should certainly be fixed
before gcc 3.2 for 3.x adoption to my mind.
