Bootstrap failures building libstdc++ on i586-pc-linux-gnu

[Art Haas <ahaas at airmail dot net>]

Hi.

For about the last week or so my builds of the 3.4 development snapshots
have failed when building libstdc++. Things fail when building the
locale-inst.cc file (things slightly reformatted for mail purposes ...)

My CVS checkout was yesterday afternoon.

Machine info: i586-pc-linux-gnu
Distribution: Debian
Kernel: 2.6.0-test3 (BK from about 1 day before -test4)
Glibc: libc6-2.3.2-2
Binutils: 2.14.90.0.6
Configure flags:
CFLAGS="-O2 -march=pentium-mmx -std=gnu99 -finline-limit=50000"
CXXFLAGS="-O2 -march=pentium-mmx -finline-limit=50000"
--enable-shared --enable-__cxa_atexit

As seen above, when compiling this file the makefile passes both CFLAGS
and CXXFLAGS variables to the compiler, so I get the warning about the
'-std=gnu99' flag. This warning is not new as I've had it for quite some
time and built successfully many earlier 3.4 CVS snapshots. The initial
bootstrap compiler was GCC-3.4 20030824, so whatever is tripping up my
build has been added within the last week.

Anyone else seeing this? If not, any ideas?

Thanks.
