I needed to build the following files with no optimisation:
smbd/fileio.c
smbd/trans2.c
smbd/open.c

Everything else was compiled with -xO4 (highest level of optimisation in
spro 2.0).

Not sure if it works yet, it could be completely broken. :-) I'll let you
know if it works, and if so, might be worth modifying the autoconf script to
check the version of spro and play with optimisation flags accordingly?
