I believe a positive but nonexistent fd passed to cygheap_getfd results in a
-1, so that case should be covered by this patch.
However I botched the coding for mq_close. That fix plus anything else needed
per reviews will appear as a v2.

See

and related.
Thanks for posting how the new behavior is different from the old.
I am having a related issue, with C++ code that parses the command line.
The command line we support is something like -
program_name arg1 -option1=v
on abstracting out the
updating of profile counters based on a thread handle.
(profthr_func): Updated to call profthr_byhandle() to sample the main
thread then call cygheap_profthr_all() to sample all other pthreads.

There is a different implementation of cpusets under libc/sys/RTEMS that
has FreeBSD compatibility and is built on top of FreeBSD bitsets. This
implementation can be com
Sorry for the repetition...

Borrow a trick from strace to lessen occurrences of "??? => ???" in ldd
output. Specifically, if the module name isn't found in the usual place
in the mapped image, use the file handle we have to look up the name.

The CPU_SET macros defined in Cygwin's include/sys/cpuset.h must not
be visible in an application's namespace unless _GNU_SOURCE has been
#defined. Internally this means wrapping them in #if __GNU_VISIBLE.

Though our implementation of cpu sets doesn't need it, software from
Linux environments expects this definition to be present. It's
documented on the Linux CPU_SET(3) man page but was left out due to
oversight.

Patched copy of NetBSD's localtime.c to hold changes that could not be
accomplished in the wrapper file localtime.cc. It is this file that
compilation of localtime.cc includes.
