Ok...
... thank you very much... :-)

I've found a couple of minor issues:
- Building on SuSE Linux 10.0 with "-D_map_libc=1" in CCFLAGS fails with
an error

- I adjusted by build script to include "-lsocket -lnsl -lrt" - the
usage of the "socket" and "nsl" libraries is a cheat to make the build
system think the network functions are available. "rt" is the Solaris
realtime library which contains functions such as |nanosleep()| and now
iffe picks this up by default, too.

- On 32bit and 64bit Solaris/SPARC the "exit.sh" test now fails with:
-- snip --
        exit.sh[59]: exit in .profile is ignored
-- snip --
Solaris i386 (32bit) and AMD64 (64bit) seem to be unaffected by this
issue.

- I found a Solaris linker option which is able to detect duplicate
symbols between libraries.
For libshell the related outout looks like this:

AFAIK the following symbols need to be added to "map.cQ", too:
-- snip --
crypt
getws
getopt_long_only
unsetenv
_filbuf
__loc1
optarg
opterr
optind
optopt
remove
setenv
setkey 
signal
getopt_long
getsubopt
encrypt
-- snip --

Notes:
- |strlcat| is already listed in "map.c" but somehow still appears as
unmapped symbol
- |optind|, |opterr|, |optopt| and |__loc1| are no functions and seem to
be tricky items to map... ;-(

I can try to make a patch for "map.c" next week (today my remote access
to the AMD64 box broken and I am away for the rest of the
weekend+monday) ...

Bye,
