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. gdb/ 2013-07-01 Pedro Alves <palves@redhat.com> * configure.ac (GDBINIT): Define, depending on host. * go32-nat.c (init_go32_ops): Don't override gdbinit here. * top.c (PATH_MAX): Delete fallback definition. (GDBINIT_FILENAME): Delete. (gdbinit): Reimplement as const char array set to the GDBINIT string constant. * top.h (gdbinit): Make const.
