Hi, continuing on the OpenBSD theme, I am seeing a couple of compilation
failures with sys/time.h, gettimeofday, and timeval very similar to one
reported recently for cygwin [1] (coincidentally I am also investigating on
behalf of Octave).
In a barebones project using gnulib-tool --with-tests --with-tests-c++
and including the gettimeofday and select modules:
$ cd tests
$ gmake -k test-sys_select test-sys_time test-sys_time-c++
CC test-sys_select.o
test-sys_select.c:44: error: size of array 'verify_tv_sec_type' is negative
gmake: *** [test-sys_select.o] Error 1
gmake: Target `test-sys_select' not remade because of errors.
CC test-sys_time.o
test-sys_time.c:27: error: size of array 'verify_tv_sec_type' is negative
gmake: *** [test-sys_time.o] Error 1
gmake: Target `test-sys_time' not remade because of errors.

There is a circular inclusion loop between sys/select.h and sys/time.h
in the system headers.
