Subject: --options to Makefile.PL completely ignored, leading to broken .so and OOMing tests
Thanks to the state of affairs with pkg-config, relying on pkg-config just breaks things!

If you've locally compiled gd without many of the image libraries:

gdlib-config --features
gdlib-config: warning: this script is deprecated; please use the pkg-config file instead.
GD_GIF GD_GIFANIM GD_OPENPOLYGON GD_ZLIB GD_FREETYPE GD_FONTCONFIG GD_XPM GD_TIFF

And, defensively, try to build GD with a similarly restrictive set of options:

/usr/bin/perl Makefile.PL --options 'VERSION_33,GD_UNCLOSEDPOLY,GD_FTCIRCLE'


Makefile.PL instead just gives you the finger and gives you a hard-coded list of features! ....

/usr/bin/perl Makefile.PL --options 'VERSION_33,GD_UNCLOSEDPOLY,GD_FTCIRCLE'
Configuring for libgd version 2.2.5.
Included Features:          GD_GIF GD_OPENPOLYGON GD_ZLIB GD_PNG GD_FREETYPE GD_FONTCONFIG GD_JPEG GD_XPM GD_TIFF GD_WEBP GD_UNCLOSEDPOLY GD_ANIMGIF GD_FTCIRCLE VERSION_33
gdlib-config used from the PATH

Unsurprisingly, this list directly corresponds with the string defined here:

https://metacpan.org/source/RURBAN/GD-2.71/Makefile.PL#L458

Extended with the string defined here:

https://metacpan.org/source/RURBAN/GD-2.71/Makefile.PL#L491

Which is basically ignoring the actual features supported by the installed gd implementation.

This unsurprsingly leads to a broken compilation of GD ( which, amusingly, compiles and links just fine )


Only to shit the bed later in tests:

Unsurprisingly, its taken me a bit to get around to triaging this problem ....

Yes, upstream is nor helpful at all. See https://github.com/lstein/Perl-GD/issues/27 An autoconf-like probe for the features is needed. If you provide the wrong options it fails. That's a limitation, not a bug. I'll check the --options handling again, what you pointed out. This could be a bug. -- Reini Urban

As long as Makefile.PL or `make` screams about it not making sense(preferably the former), I don't mind *so* much, but only failing tests ... I mind a bit more.
