Suggested by Shaun Jackman <sjackman@gmail.com>:
* defs.h (print_transfer_performance): Update prototype.
* m32r-rom.c (m32r_load, m32r_upload_command): Use gettimeofday
for print_transfer_performance.
* remote-m32r-sdi.c (m32r_load): Likewise.
* symfile.c (generic_load): Likewise.
(report_transfer_performance): Create a dummy struct timeval.
(print_transfer_performance): Use a more accurate measure
of performance.
