Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Emacs trunk cannot to be build on FreeBSD with the follwing error. 

/usr/lib/gcc/i686-gentoo-freebsd7.2/4.4.3/../../../../i686-gentoo-freebsd7.2/bin/ld: cannot find -ltermcap
collect2: ld returned 1 exit status
gmake[1]: *** [temacs] Error 1
gmake[1]: Leaving directory `/usr/local/src/bzr-src/emacs-trunk/src'
gmake: *** [src] Error 2

Rev 99699 removed "#include <osreldate.h>", but this line is necessary
to define __FreeBSD_version. Without the line, "#if __FreeBSD_version
< 400000" always succeeds and cause "#define LIBS_TERMCAP -ltermcap"
which is not adequate library.

With the attached patch, I was able to build emacs on FreeBSD again.
