Sun Solaris 2.7
>Description:
I don't even know whether this is a bug, the docs are very
brief on that, nevertheless: on Sun, gcc2.95 searched
/opt/SUNWspro/lib for libraries given with -l on the link
line, while gcc3 does not do that any more. It's a little
annoying but not that important. There's a more important bug
lurking around the next corner, but see next report.
