My suspicion is that the presence of -I/usr/include is causing the
problem; it typically results in Solaris' stdarg.h (which isn't
compatible with gcc) being used instead of gcc's version.

This appears to be due to the following lines in
include/Make/Platform.make.in:

PNGINC = -I/usr/X11R6/include/ -I/usr/include/gr -I/usr/local/include -I/usr/include
PNGLIB = -L/usr/local/lib -L/usr/X11R6/lib -L/usr/lib

I suggest that you change these lines to:

PNGINC = @PNGINC@
PNGLIB = @PNGLIB@

then re-run configure and re-compile.

In turn, this gives rise to two questions for Radim:

1. Why are these paths hardcoded, instead of using the values from the
configure script?

2. Why is $(PNGINC) being used for compiling libgis?
