[Bug target/13093] New: non-relocatable subtraction expression, "L3$pb" minus "LSJR11"

[gcc at microbizz dot nl]

See the thread "PR target/10129 ADA bootstrap failure on Darwin on
powerpc-apple-darwin" on the gcc-patches list
<http://gcc.gnu.org/ml/gcc-patches/2003-07/msg00171.html>.

With Pascal, based on gcc-3.3.2, I run into a similar problem on
powerpc-apple-darwin. See below.

S i d e b a r
The extra compiler argument passed (--longjmp-all-nonlocal-labels) is needed
because PR 10901 is still open. In fact, the compiler argument has only been
created because nonlocal goto's tend to be broken in gcc. With some luck, we get
a fix for some platform in some version of gcc, but invariably the problems come
back for some other platform in a later version of gcc.
E n d   S i d e b a r

The workaround, by the way, is to pass -O2 instead of -O3.

Not to be fixed for 3.3 as it is not a regression as setjmp was not working correctly before then.
Fixed already for 3.4.

Thanks for looking into this. I didn't know that it was fixed in 
gcc-3.4 already.

The patch provides a way to fix this in gcc-3.3.x. So, although it 
won't be fixed in the gcc 3.3.x branch, there is at least a separate 
patch available, which I thought is a useful piece of information to 
attach to this PR.
