to use it but to not do heap corruption checking.
* gdbserver/Makefile.in: Ditto.
* utils.c (init_malloc): Replace warning() use with direct call of
fprintf_unfiltered, since current_target has not yet been set and thus

saved pc. Real hardware does this for you.
* sh3-rom.c (sh3_load): New routine. Sets up for download then
calls generic S-record loader.
* config/h8300/h8300.mt, config/h8500/h8500.mt,
