The eCos 3.0 tested itself about a few months. It not seems, that
maintainers missed the posix things. What template did you use? Lazy
demos with the latest eCos 3.0 are the below (run on Linux host)

Synthetic target:

/tmp/foo$ . /opt/ecos/ecosenv.sh 
/tmp/foo$ echo $ECOS_REPOSITORY 
/opt/ecos/ecos-3.0/packages
/tmp/foo$ ecosconfig new i386linux posix
U CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT, new inferred value 0
U CYGBLD_ISO_STRUCTTIMEVAL_HEADER, new inferred value <cyg/posix/sys/time.h>
U CYGNUM_LIBC_MAIN_DEFAULT_STACK_SIZE, new inferred value 16384
/tmp/foo$ ecosconfig tree
/tmp/foo$ make -s headers
headers finished
/tmp/foo$ find -name time.h
./install/include/sys/time.h
./install/include/time.h
./install/include/cyg/posix/sys/time.h
./install/include/cyg/posix/time.h
/tmp/foo$ make -s -C io/fileio/v3_0
/tmp/foo$ 

No errors.

ARM target:

/tmp/bar$ ecosconfig new pid posix
U CYGBLD_ISO_STRUCTTIMEVAL_HEADER, new inferred value <cyg/posix/sys/time.h>
/tmp/bar$ ecosconfig tree
/tmp/bar$ make -s headers
headers finished
/tmp/bar$ find -name time.h
./install/include/sys/time.h
./install/include/time.h
./install/include/cyg/posix/sys/time.h
./install/include/cyg/posix/time.h
/tmp/bar$ make -s -C io/fileio/v3_0

No errors.

Well done, just 1 warning.

I noticed that you use old arm-elf toolchain. Do you have a reason for that?
