Bug 1439: The POSIX standard did not distinguish object and function pointers as did the C standard.  Rejected
https://austingroupbugs.net/view.php?id=1439

This was discussed in the October 21, 2021 teleconference and the
consensus was that no change to the standard is needed. POSIX allows
platform-specific ABIs to require function and data pointers to
have the same representation and address space, so there is no
conflict with existing ABI specifications. There is no clear need
for a portable mechanism to execute mmap()ed memory, so POSIX does
not need to explicitly permit conversion of the mmap() return value
to a function pointer. The siginfo_t::si_addr data member is used
for implementation-specific debugging (note the sentence in
POSIX.1-2017 XBD chapter 13 <signal.h> on page 338 line 11452: "For
some implementations, the value of si_addr may be inaccurate."),
so no change is needed to enable portable conversion of this void*
data member to a function pointer.

Bug 1440: Calling `system("-some-tool")` fails (although it is a valid `sh` command)
https://austingroupbugs.net/view.php?id=1440 OPEN

This was discussed and will be continued on the next thursday call.
