	The previous testsuite run was about 12 hour before.  There were
no fortran or libgfortran changes during that period, except possibly
Volker's diagnostic patch.

	There were a number of C patches during that time, so it is
possible that libgfortran is being miscompiled for AIX.  libgfortran does
not use mmap for I/O on AIX, unlike most of the other systems.
