/* GCC 2.95.3 emits the first N_SLINE stab somwehere in the
middle of the prologue instead of right at the start of the
function. To deal with this we record the address for the
first N_SLINE stab to be the start of the function instead of
the listed location. We really shouldn't to this. When
compiling with optimization, this first N_SLINE stab might be
optimized away. Other (non-GCC) compilers don't emit this
stab at all. There is no real harm in having an extra
numbered line, although it can be a bit annoying for the
user. However, it totally screws up our testsuite.
So for now, keep adjusting the address of the first N_SLINE
stab, but only for code compiled with GCC. */
