4.4 deprecation patches

4.4 deprecation patches

[Joseph S. Myers]

These patches implement the deprecations discussed at 
<http://gcc.gnu.org/ml/gcc/2008-06/msg00324.html> of various targets and 
the protoize and unprotoize utilities.  OK to commit?

Of the targets listed there as still using fixproto, hppa[12]*-*-hpux10* 
has had its fixproto use removed so it is not on the deprecation list.  I 
encourage anyone using GCC for IRIX, 2BSD or AIX 4.1 and 4.2 to stop those 
targets from using fixproto (possibly just removing the use_fixproto 
setting, possibly adding new fixes to fixincludes to replace any important 
changes fixproto made) and to remove the deprecations at the same time.  
(Please also send your test results to gcc-testresults if you are using 
one of those targets.)

Deprecation of targets not converted to IRA will wait until after IRA is 
on trunk and the old allocator is removed.

I don't know whether this counts as an "algorithmic" change or not.
I'm approve it in case it does not.

Thanks.

I'd like to ask the H8 not be deprecated -- we still occasionally get 
submissions for the H8 port.  I'll volunteer for the IRA conversion of 
the H8.

The only H8 deprecation proposed (as long as it's converted to IRA) is the 
generic COFF target, which is all target triplets matching h8300-*-* that 
don't match h8300-*-rtems* or h8300-*-elf*.  Do you have a continued use 
for this COFF target?

For avoidance of doubt, I approve the patch.

My bad.  I missed the fact that it was just the coff targets.  I can't 
recall the last time anyone used h8300-coff or h8300-hms.
