David,

sorry for the late reply.

I'm quite ashamed to tell I just ripped out the "_long" from getopt_long, so
some options are not available from the resulting binaries. I just wanted to get
a working binary first.
Diff is attached.

Adding gnulib to src/Makefile.in for libfa make the thing compile and
run with segfaulting:

libfa_la_LIBADD = $(GNULIB)

Had to force make to use the gnu ld instead of the AIX ld. AIX ld gave me:

Building on Solaris 10 was actually quite easy. The only thing I had
to change was making sure
gnulib was linked into libfa.

I just changed src/Makefile.in to read:

libfa_la_LIBADD = $(GNULIB)

This should probably be done  in Makefile.am though.

I compiled with gcc 3.4.5 and used the native Solaris ld.

I meant to say sudoers file is the same on both Linux, Solaris, AIX, ...,
as is the aliases file. So the lenses that work for these files on Linux should
give me no problems on Solaris, AIX.

Did that, output in attachment. But I am really not qualified to
interpret what gdb spits out.

Kind regards,
