[ECOS] how to link "gettimeofday" with arm-elf-gcc?

[Yusuke Matsuoka]

Hi Andrew and Gary,

Thanks for the reply.

I want to run the KVM(K virtual machine for Java) on eCos and
want to measure the exec time of my Java application on the board.
The original KVM implementation uses "gettimeofday", and I got
the linker error.

Since I need a *millisecond* resolution, is there a better way 
rather than including snmp?
I want to keep the footprint small.
(ctime(time()) is a *second* resolution, right?)

Thanks,
Yusuke
