>Description:
1) Upgrades from gcc 4.6.2 to gcc 4.6.3
2) Splits off Makefile.common fragment for use in other ports
3) Adds post-install warning that Ada tasking is broken for FreeBSD 9+

Regarding #3: Due to a new panic assertion added to the thread library, exiting tasks now abort with the message "thread exits with resources held!".  A significant attempt was made to patch GNAT to release thread resources on exiting tasks, but the code is highly complex and the attempts are not yet successful.  Things to note:

A) gnat-aux continues to work on FreeBSD 6.x, 7.x, and 8.x.
B) gnat-aux has always been broken on FreeBSD 9.x, but a testsuite run didn't reveal this until recently
C) gnat-aux didn't change, FreeBSD did.  It considers something a fatal error that was acceptable before and doesn't leave any method to degrade back to FreeBSD 8.x behavior other than rebuilding libpthread from source with _PTHREADS_INVARIANTS undefined.
D) A new version of gnat-aux based on gcc 4.7 will be needed to convince Adacore to take this issue seriously as it affects all POSIX platforms.  FreeBSD is the only one to detect the held resources.  (Still, the decision on the part of FreeBSD developers to make this a fatal panic is questionable).

>How-To-Repeat:
Regarding the FreeBSD 9.0 failures, 23 tasking test failures can be seen by doing "make test" from lang/gnat-aux.
>Fix:

 Hi John,
 
 thanks for this update and for your work on gnat-related ports.
 
 However, I came into trouble here when trying to apply the diff-fortran
 patch. Indeed, it seems it doesn't find the files to patch in the testsuite
 (large_real_kind*). When taking a closer look at the patch it tries to apply, it
 seems to me that it's related to {dragonfly,net}BSD, so I am not sure we need
 those here.
 
 A tinderbox error log could be found here:
 
 https://redports.org/~culot/20120407144819-41367-19024/gnat-aux-20120301.log
 
 Could you please check this issue and make sure that only FreeBSD-specific
 patches are included?
 
 Thanks again for your hard work!
 
 Cheers,
 Frederic

 Well, I'm trying very hard not to have different versions here for 
 configuration control reasons.  The diff-* files are the same for all 
 platforms by design.
 
 In this case, it seems like wrong diff file has the patches though.  It 
 should be diff-fortran-testsuite, not diff-fortran, that has these.  The 
 same upgrade has been on pkgsrc for weeks without a failure so this is 
 curious.  Let me compare versions because this is curious.  I didn't see 
 it during my testing because I always had at least one testsuite being 
 requested...

 Hi Frederic,
 I compared the contents of files/ with the pkgsrc version and discovered 
 the files/diff-fortran I provided is wrong.  This file was the only 
 difference.  If you replace it with the version found below, it should 
 work as expected:
 
 https://raw.github.com/jsonn/pkgsrc/trunk/lang/gnat-aux/files/diff-fortran
 
 Also, if you inspect files/diff-fortran-testsuite, you should see the 
 large_real_kind patches there already.
 
 Regards,
 John

 By the way, it may be that the pkgsrc diff-fortran is identical to the 
 current lang/gnat-aux version, so replacing actually just restores it.
 
 So only diff-ada and diff-core would change between gcc 4.6.2 and 4.6.3.

   Modified files:
     lang/gnat-aux        Makefile distinfo 
     lang/gnat-aux/files  diff-ada diff-core 
   Added files:
     lang/gnat-aux        Makefile.common 
   Log:
   - Update to 20120301 (corresponding to gcc 4.6.3)
   - Split off Makefile.common fragment for use in lang/gnatdroid-arm* ports
   
   Maintainer note:
   - Ada tasking is broken on FreeBSD-9+ and has always been but a testsuite
   run didn't reveal this until recently. Due to a new panic assertion added
   to the thread library, exiting tasks now abort with the message "thread
   exits with resources held!". A significant attempt was made to patch GNAT
   to release thread resources on exiting tasks, but the code is highly
   complex and the attemps are not yes successful.
