we've had compile-problems (well, i have) related to smbencrypt.c and a
couple of other files, before.
no reports or occurrences for over two years, though.
i suggest you try compiling without -O2, with -g, with neither etc.
also, a pain-in-the-neck process that i had to use to narrow down compiler
problems before (lattice c compiler for the atari st!) was to do a binary
search, removing functions.
in this case, you'd have to move them to... smbencrypt1.c otherwise you'd
not get a link.
