Hello,

after compiling a small test program with gcc 2.7.0, which does basically lots 
of floating point additions and multiplications (and load from array), I noticed
that it runs 15% slower than it used to.

The result is the same to 12 digits (all that are printed).

Whats wrong?

Solaris 2.1:  it's slow, needs 200M of disk space and comes without C compiler,
which makes it remarkably close to MS-Windows. oleg@gd.cs.csufresno.edu
