 Hi,
 
 Brad, if the phenomenon is that all the *.ali compiled by gnatgcc
 contain just a single linefeed or similarly truncated output, then
 gnat1 may have been miscompiled (either now or formerly).  I have
 experienced that with the stage1 xgcc from the gcc-3_2-branch when I
 used STAGE1_CFLAGS="-march=i686 -O2". Apparently, either Debian's
 gcc-2.95.4 or the gnatgcc v2.8.1 (plus GNATBIND v3.14p (20010503))
 used for bootstrapping did not do a good job with that option. When I
 removed the "-march=i686", everything went fine.
 
 NB: The problem occurs on gcc-3_2-branch only (including the 3.2.2
 release); it has not shown up with checkouts of 3.3 or 3.4 (mainline).
