This is a bit of a mixed bag update, I'm hoping to fix the intermittent
build problems, make gnat more useful, and include Pascals -rdynamic
diff since that requires a revision bump as well and is useful in any
case.
This patch set survived ~35 test builds of 4.6 and 4.8 on i386 in
addition to three builds per adastrap.
OK?
Some comments inline:
Details:
* Enable -rdynamic in 4.8, from pascal@
* Switch all architectures to setjump/longjump exceptions because of
suspected problems with ZCX.
* Call __errno() from librthread when using pthreads (Tero Koskinen)
* Enable gnat shared library support for OpenBSD (Tero Koskinen)
* Provide OpenBSD specific OS support, including struct layout fixes.
* Sync 4.6 with the changes done to 4.8

Is this true on OpenBSD as well? (On another note, you may want to
