posix_spawn issue?

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

NetBSD implements posix_spawn() and Linux does too.

gmake since version 4.3 uses posix_spawn(), but that breaks the build
of firefox (and libreoffice). Disabling posix_spawn() support in gmake
works around this problem.[1]

Is there a bug/incompatibility in our posix_spawn() or is there a bug
in gmake?

If you want to try it out, use wip/gmake and remove the
CONFIGURE_ARGS.NetBSD+=	--disable-posix-spawn
line.

Cheers,
 Thomas
