This is the configuration problem for newlib 1.8.0 which I have already
sent a patch in for.  The error is the setting of target_cflags in
newlib/configure.in.  It needs to be:

target_cflags="${target_cflags} -DHAVE_GETTIMEOFDAY -DMALLOC_PROVIDED -DEXIT_PROVIDED -DMISSING_SYSCALL_NAMES -DSIGNAL_PROVIDED
-DREENTRANT_SYSCALLS_PROVIDED"

This patch may be necessary for other targets but not for RTEMS
specifically.

FYI RTEMS does have support for POSIX style signals -- you just have to
enable POSIX when you build RTEMS.
