[M3devel] stack walker vs. gcc 4.5

[Jay K]

I'm really really really really really really inclined to ditch using the one stack walker we use: SOLgnu/SOLsun/SPARC32_SOLARIS.
 I have been trying for quite a while to get it to work with the gcc 4.5 backend with no luck.


We could/should use the gcc exception handling support, thereby getting stack walking for most/all platforms.


Though odds are probably higher of generating C++ source and using exception handling there, and again, getting stack walking.
  (Or C on VMS/NT/OSF1 since they all have exception handling in C; NT/x86 doesn't really do stack walking, but
an optimized form of our non-stackwalking implementation)
