bglibs-1.024 make problem on FreeBSD 5.4p5

I had a bit of trouble making bglibs last night, and thought the
solution might be useful to someone else, so here's the info.  BTW -
this is the first time I've ever built bglibs by hand, so I may have
made a trivial mistake somewhere, please correct me if you see it one.

uname -a:

Full output of the make command is located at:

The relevant portion is:

./compile bg-installer.c

The file unistd.h is: <http://weller-fahy.com/errors/unistd.h>

After digging through the bg-installer.c and unistd.h files, and finding
what I believed to be the problem, I ran 'grep -r setmode *' in the
bglibs, cvm, and mailfront source directories.  The only relevant hits
were in bg-installer.c, so I changed all instances of the function name
'setmode' in bg-installer.c to 'bgsetmode'.  That allowed it to make,
and install.

The patch I created using 'diff -uBb' (trivial, probably doesn't need to
be a patch) is: <http://weller-fahy.com/errors/bg-installer.c.patch>

However, I wanted to make sure that changing the name of setmode would
not have some unexpected consequences down the road, and bring this
error to the attention of the author, so here I am.

So, is there anything else I should have done to fix the problem?  If
so, what is the correct solution?  Or was changing the function name
correct?
