I took the easy out and just commented out the three offending declarations -
be careful if you change compiler versions (xlc/cc/c89 and so on), as that may
change things around...

I seem to remember libtiff being a long afternoon's worth of porting, as
it took multiple iterations to stamp out all the sillyness in the libtiff
headers..

Hard to diagnose without seeing the actual error messages, but it's
probably libpng not expecting to be built with xlc (it's either making a
lot of unwarranted gcc assumptions, or wants a different alias for the
compiler).

I don't remember libpng as being a particularly difficult port to AIX,
even using the 'xlc' alias for the compiler...

Quite frankly, you probably need to visit bullfreeware.

Alternatively, you might want to re-evaluate your product direction - if your
in-house AIX expertise wasn't able to figure out the libtiff and libpng issues,
you may be in trouble there.  In addition, there seems to be weakness on
the Linux, Solaris, and Irix platforms as well:

> -Linux: Dependency libpng-1.2.5 cannot compile:

Almost certainly a misconfiguration causing an #include inside a #ifdef to be missed,
which resulted in a missing C 'struct' definition.  I can't speculate more
without looking at the png.c source.

Repeat after me:  "If configure fails, look in config.log".

What distribution/release of Linux was this on?  gexttext *should* be
in any recent glibc release (note that glib and glibc are two different things
entirely).

You should be able to just install gtk and all its pre-requisites on most
Linux distributions - RedHat, Debian, and Suse all support gtk "out of
the box".

The Sun C compiler wants to see -O, not -O3.  Were you using a makefile
that assumed that gcc was the compiler, or was it just a botched setting
of CFLAGS?

1) You're using gcc here, but cc for libpng - unclear why the change.
2) The reference to glib-1.2.8 looks like an upper-level Makefile passing
bad values for CFLAGS and/or LDFLAGS...
3) the setresuid() issue smells of a broken configuration - I suspect you
copied over a source tree from a Linux (or possibly *BSD) box, and
failed to re-run './configure' on Solaris....

Time to visit the SunFreeware site, I suspect...

Yowza.  I have *no* idea what you managed to do here....

And yes, SGI has a Freeware site with this sort of stuff already on it...
