egcs-20000520 g77 bug on i686-pc-cygwin and i686-pc-linux-gnu -Os -funroll-loops

[N8TM@aol.com]

With recent improvements, the attached code runs correctly (but not fast) at 
-O -funroll-loops and at -Os. The ICE
at -ffast-math -march=pentiumpro remains (same as the one in LAPACK).  When 
compiled with gcc-2.96 -g -Os -funroll-loops, setting a
breakpoint at line 2079 (right after the assignment jn=n) jn is found set to 
6, while n is set to 100.  This appears to account for
the erroneous results obtained in the following loop.
