# This causes pngpriv.h to include the named header.  It is VERY important to
# understand that this MUST be defined and the header MUST define internal
# 'extern' functions with PNG_INTERNAL_FUNCTION.  This allows vendors to use
# static library builds of libpng without clashing with the installed system
# libpng; see the libpng-prefix option in configure.ac  The value of this
# #define is included in pnglibconf.h
#
# NOTE: you must include the double quotes in the value and you must therefore
# support the whole thing with single quotes.  If you need to use <> for a
# header be aware that if you miss out the single quotes you will create a
# random file.
