I wan't able to reproduce your problem. For starters, the versions of
gcc-2.95 I have easy access to wouldn't compile your testcase. Due
to an interaction between -fprefix-function-name and naming functions
with asm ("name"), the assembly output used names like
chkr.*main
which the assembler doesn't like at all. OK, so I fixed this gcc bug

and then the testcase compiled and linked without errors. This was
using current CVS versions of gcc-2.95 and mainline CVS binutils.
