Log Message:
Updated to version 2.35.

Pkgsrc changes:
  - The package uses a C compiler.
  - Removed unnecessary :M* modifier (pkglint gave the hint).

Changes since version 2.30:
=====================================
2.35	Some instructions on installation for Windows users.
	Doesn't push libpng onto @LIBS unless png support is requested.
	Supports Storable's freeze/thaw via a custom serializer.
	Remove "scale redefined" message during compilation of Polyline.
2.34    Added a check for stray gd.h include files from older installations.
	If any are found, Makefile.PL will issue a warning.
	Fixed incorrect documentation of GD::Simple->string() method. The
	method call *does* move the pen.
2.33	Added appropriate #ifdefs to allow to compile under version 5.6.0
	(due to lack of threading macros before 5.8).
2.32	Added a GD::Simple->HSVtoRGB() method.
	Documentation fixes from Mark Manning.
	Added a clear() method to GD::Polygon to remove all vertices.
2.31	Fixed GD::Simple->transparent to support symbolic color names.
	Made changes that should render the module thread-safe.
	Changed newSVpv calls to newSVpvn, in hopes of improving performance.
	Added a GD::Simple->HSVtoRGB() method.
	Fixed incorrect freeing of user-provided raw data in newFromGdData()
	and newFromGd2Data() (this caused segfaults; patch provided by
	Nigel Sandever)
