The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.

/* Convert SIM_SIGFOO to SIGFOO.

What to do when the host doesn't have SIGFOO is handled on a case by case

basis. Generally, in the case of passing a value back to gdb, we want gdb

to not think the process has died (so it can be debugged at the point of

failure). */
