Here's how it works. There is a .h and a .c file for each object file -format, a .h and a .c file for each target processor, and a .h for -each host. config.gas creates {sym}links in the current directory to -the appropriate files in the config directory. config.gas also serves -as a list of triplets {host, target, object-format} that have been -tested at one time or another.

It is intended to -be used to hide host compiler, system header file, and system library -differences between host machines. If your host needs actual c source -files, then either: these are generally useful functions, in which -case you should probably build a local library outside of the gas -source tree, or someone, perhaps me, is confused about what is needed -by different hosts. - obj-format.h is a {sym}link to .../config/obj-something.h.
