[PATCH] Abandon gcc-2.95.x

Andrew Morton · Linus Torvalds · commit fd285bb54d8a · 2006-01-08T20:14:02.000-08:00
There's one scsi driver which doesn't compile due to weird __VA_ARGS__ tricks
and the rather useful scsi/sd.c is currently getting an ICE.  None of the new
SAS code compiles, due to extensive use of anonymous unions.  The V4L guys are
very good at exploiting the gcc-2.95.x macro expansion bug (_why_ does each
driver need to implement its own debug macros?) and various people keep on
sneaking in anonymous unions, which are rather nice.

Plus anonymous unions are rather useful.
