__CONCAT does token pasting, not string concatnation. if something like:
...
__CONCAT("PATH=",_PATH_STDPATH);
actually works to concantate strings, it's because the preprocessor expands
it into "PATH=""whatever _PATH_STDPATH is" as separate strings, and then
ANSI string concatenation is performed on that. It's more straightforward
to just use ANSI string concatenation directly, and newer GCCs complain
(rightly) about mis-use of token pasting.

PR/11283: Hubert Feyrer: random memory corruption executing commands:
...
Fix from FreeBSD:
growstackblock() sometimes relocates a stack_block considered empty
without properly relocating stack marks referencing that block.
The first call to popstackmark() with the unrelocated stack mark
as argument then causes sh to abort.
Relocating the relevant stack marks seems to solve this problem.
The patch changes the semantics of popstackmark() somewhat. It can
only be called once after a call to setstackmark(), thus cmdloop() in
main.c needs an extra call to setstackmark().

The setstackmark()/popstackmark() pair in dotcmd(), used for freeing

PR/6213: Urban Boquist: /bin/sh does not handle a trapped signal correctly
...
The problem was that system calls got restarted after a signal,
instead of returning EINTR. Thus the read builtin, had no way to
know that a signal occured that could change the course of execution.
Since the code has sprinkled checks for EINTR all over the place,
it is supposed to work properly with non restartable syscalls.
The fix is to use siginterrupt(signo, 1), before setting a signal
handler, to make sure that system calls don't get restarted.
