WEll...Atleast it doesn't blow up anymore.

Now it just 'skips' the text part. Haven't looked at the code changes yet
so not sure what/why. Really though it's still broken for this case. I
have to get to the root of it. It seems like theres a problem with how
ext/gd/config.m4 is handling things because the USE_GD_mumble gets defined
even though none of those three functions are HAVE'd. In our situation I
think they should be somehow but I'm not sure why they aren't.

I've made a note/comment in the bug itself but figured I should post it
here too.

This bug is NOT yet fixed.

In 4.3.1 the code can and still does produce bogus code that doesn't set
error.

my main/php_config.h generates with this area (not verbatim):

/* /
/ #undef HAVE_GD_STRINGTTF */

/* /
/ #undef HAVE_GD_STRINGFT */

/* /
/ #undef HAVE_GD_STRINGFTEX */

/* */

define USE_GD_IMGSTRTTF 1

/* */

define USE_GD_IMGSTRTTF 1

Notice we have neither FT nor the FTEX, nor TTF!

So why in the world does USE_GD_IMGSTRTTF get 1? TAke a look at
gd.c:2937

In this case error still ends up undefined as we never execute any of
the four functions!!!! I traced the calls back up, the bt is included
below along with a print error to point out the fact.

Essentially no change, teh problem with the #ifdef's is still there. Now
*error is just initialised to NULL so it runs, but is effectively a NOP
because none of the TTF funcs before get called (IE same problem, better
error condition handling, and therefore different symptoms)
