No.  What does that do, and what would I be looking for?

Many of the signal and errno numbers are different.  A few of the
other sigaction bits are different.  Those are the main bits.

Alpha does not have SIGUNUSED, SIGLOST, or SIGSTKFLT.  Neither do
many other Linux targets, but s-osinte.adb isn't correct for them.

Except for Tick, all little-endian 64-bit Linux targets should be
the same.  Add Bit_Order and all 64-bit Linux targets should be
the same.  Add the <limits.h> equivalent bits, and *all* Linux
targets should be the same.

Yet more reasons that all of this data should be extracted from
/usr/include instead of specified by hand.
