[c++] gcc-2.96/gcc-2_95 -ffunction-sections -fvtable-gc -fPIC bug

[Benjamin Kosnik <bkoz@cygnus.com>]

-fPIC -ffunction-sections -fvtable-gc doesn't seem to play nice with
 this code, I get:

%g++ -c func-secs.cc -fvtable-gc -ffunction-sections -fPIC
func-secs.cc: In function `void __length_error(const char *)':
func-secs.cc:43: warning: asm operand 0 probably doesn't match constraints
cc1plus: inconsistent operand constraints in an `asm'

-fPIC alone, or -ffunction-sections -fvtable-gc alone work well.

However, the combination is no bueno.

This is for current egcs/gcc-2_95, tested on x86/linux.
