BFD keeps one atom in a BFD describing the
architecture of the data attached to the BFD: a pointer to a

Pointers to structures can be requested independently of a BFD
so that an architecture's information can be interrogated
The set of default architectures is selected by the macro
<<SELECT_ARCHITECTURES>>. This is normally set up in the
@file{config/@var{target}.mt} file of your choice. If the name is not
- defined, then all the architectures supported are included.

When BFD starts up, all the architectures are called with an
