	gdb            : ChangeLog config.in configure configure.ac 
	                 go32-nat.c top.c top.h 

Log message:
	Reimplement DJGPP's .gdbinit -> gdb.ini renaming.
	
	This simplifies the .gdbinit filename selection logic.
	
	We have a GDBINIT_FILENAME define that supposedly configurations would
	override, but none do so.  Instead, the only configuration that wants
	a different file name instead of ".gdbinit", djgpp, does a strcpy over
	the gdbinit global array.  This means the array needs to be sized, and
	the code that does that is doing the usual
	'PATH_MAX/FILENAME_MAX/fallback constant/etc.' mess.
	
	Instead of all that, it's much simpler to have configure specificy the
	.gdbinit filename.  As bonus, we can then make the "gdbinit" global
	array const.

	(GDBINIT_FILENAME): Delete.
	(gdbinit): Reimplement as const char array set to the GDBINIT
	string constant.
