Upgrade to Groff 1.19.

Revert the last change and mark the program as PROG_CXX.

Add -lstdc++ to the link args for these C++ tools so that they can be
compiled with gcc-3.1. Somebody thought it was a good idea to move
the implementation of new and delete from libgcc to libstdc++. This
change doesn't harm the current compiler in the tree.

Upgrade to Groff 1.17.
