No, that is the point exactly... I know fine well the visibility of
errno and the different ways it may be implemented. You'll find it
hard to come across an OS which doesn't "do the right thing" WRT to
using reentrant functions and "wrappers" if _REENTRANT is defined
during the compile...
That is ALL that is needed, lets not complicate the issue...
And what do you mean by "threaded libpq" and "non-threaded libpq" - as
I say above there are NO thread primitives being used in libpq. It's
just clean reentrant code... This change/patch should be done
irregardless of the move to thread safety!
