[Bug debug/38896] New: [4.3 Regression] building libstdc++ stumbles on "invalid bignum", 0x8000000000000000

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Attached is locale-inst.ii for gcc-4_3-branch revision 143448.
The assembler says, during build:
locale-inst.s: Assembler messages:
locale-inst.s:192360: Error: bignum invalid

The line, with context, is (with -dA -mpdebug for improved clarity, but causing
the line number to change to 203626):

The number -9223372036854775808 is also known as 0x8000000000000000.

I've been able to build for this target on the gcc-4.3 branch before.
