i686 bootstrap ICE on div_di3, 11981101 versions

[tprince@cat.e-mail.com]

Compiling on NT4/SP3, cygwin-b20 (problem seen also on b19
with NT and W95):

egcs-19981101 snapshot produces ICE when stage1/xgcc
attempts to compile div_di3 with BOOT_CFLAGS= -Os or -O2.

Egcs-1.1.1-prerelease does not show this problem at -Os but
aborts likewise when built at -O2.  Apparently, a totally
satisfactory build and install is possible at -Os.

Problem is associated with compiler build optimization level, not
with level of optimization used when compiling div_di3.
