811 /* Some parts of gdb might be considered optional, in the sense that they
812 are not essential for being able to build a working, usable debugger
813 for a specific environment. For example, the maintenance commands
814 are there for the benefit of gdb maintainers. As another example,
815 some environments really don't need gdb's that are able to read N
816 different object file formats. In order to make it possible (but
817 not necessarily recommended) to build "stripped down" versions of
818 gdb, the following defines control selective compilation of those
819 parts of gdb which can be safely left out when necessary. Note that
820 the default is to include everything. */
