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