These changes abolish M4 preprocessing for the GDB manual.
Formatting these files now depends on the recently designed
Texinfo conditionals: to format successfully, you must use very
recent versions (not yet distributed by FSF) of texinfo.tex and makeinfo.c.
The new Texinfo commands are @set, @clear, @ifset, @ifclear, and @value.
Recent texinfo-2 Beta distributions contained partial implementations.
texi2roff does not yet support these commands.
