BUG in Compiling Glibc 2.0.102 time/strptime.c

[root]

Here the output from the make process(the compiler is pgcc-2.91.57):
========================================

strptime.c: In function `strptime_internal':
strptime.c:729: fixed or forbidden register 3 (bx) was spilled for class GENERAL_REGS.
This may be due to a compiler bug or to impossible asm
statements or clauses.
make[1]: *** [strptime.os] Error 1
make[1]: Leaving directory `/root/glibc-2.0.99/time'

I attach with this mail the gunzipped source.
