configure: WARNING

[Juergen Rose]

Hi,

calling ./configure --prefix=/usr --sysconfdir=/etc --with-libxml2 in
.../AbiWord/abiword-1.99.2/wv I get:

checking pngconf.h presence... yes
configure: WARNING: pngconf.h: present but cannot be compiled
configure: WARNING: pngconf.h: check for missing prerequisite headers?
configure: WARNING: pngconf.h: proceeding with the preprocessor's result
