*cc1:
-fno-strength-reduce

*cc1plus:
-fno-strength-reduce

Please note that you must replace the empty line with '-fno-strength-reduce'.
If you add it instead the compiler complains about a corrupted specs file.
What kind of parser is this relying on fixed lines. I suggest skipping
the *cc1: and *cc1plus: keywords altogether in 2.7.3 ;-)

: BTW: Is '-fno-strength-reduce' still necessary on x86 machines
: with gcc 2.7.2? There was a bug in the code generator with this
: option turned on.

In case you want correct code, it is still necessary.

Ciao,
Michael
