[RFA/doco] document gdb.init check only performed in home directory

[Joel Brobecker <brobecker@adacore.com>]

Hello,

One of my coworkers working on Windows pointed out that GDB wasn't
warning him if a gdb.ini file existed in the current directory.
The documentation is a little ambiguous and might be suggesting that
GDB checks all locations where a gdbinit might be located for gdb.ini
files.

As far as I can tell, the use of gdb.ini for Windows was discontinued
around the end of 2001. I really don't see the point of adding even
more code to try to warn users about a file that we haven't used in
over 10 years. For now, I suggest the attached patch, which just
clarifies the current situation regarding this warning.

gdb/doc/ChangeLog:

        * gdb.texinfo (Startup): Clarify scope of gdb.ini warning for
        Windows ports.

Tested on x86_64-linux. OK to apply?

Thanks,
-- 
Joel
