One procedural nit. Please drop that "From:" immediately before
S-o-b: from future submissions (I'll remove it locally for this
patch and others you already posted when I apply, so this alone is
not a reason to resend them). If you are forwarding somebody else's
patch, you would want "From:" in body, but the correct place to do
so is before everything else, i.e.
... your e-mail headers ...

Also, please leave the "autodetection" out. If it is common to have
strcasestr (or any other) on a newer QNX, then not defining the
symbol NO_STRCASESTR in this file may still be the right thing to
do, but the justification for such a change should not be because we
rely on "autodetection". The defaults given in config.mak.uname is
primarily for people who do not use the optional ./configure script,
so pick the default to help the most common configuration for the
platform.
I'd rewrite the patch like the attached, and tentatively queue the
patch to 'pu', but I do not use or have access to QNX myself, so you
may have to adjust the default set of symbols and the log message
and in such a case, please do re-submit a fixed version.
Specifically, I do not know if "... and others are also supported"
is universally true with QNX 6; if not, we need to define NO_* for
them to help people who build without using the ./configure script.
Thanks.

Subject: [PATCH] QNX: newer QNX 6.x.x is not so crippled
The initial port to QNX declared that the platform does not have
support for pthreads, getpagesize, strcasestr, mkstemps, mkdtemp,
strlcpy, and iconv, but QNX 6.x.x does support these.
On the other hand, older QNX lack gettext support, so define
NO_GETTEXT for them.
Also newer QNX do not need to link to any special library to enable
pthreads; define PTHREAD_LIBS to an empty string.
