Linking statically against GraphicsMagick: problems with libxml2 and libpng

[Dmitry Katsubo <dma_k at mail dot ru>]

Dear CygWin users / developers!

While trying to link statically my application against GraphicsMagick
under CygWin, but I suffer from few minor problems during linking.

To discover the library list, needed for static linking, I use
"GraphicsMagick++-config --libs":

> configure:7259: g++ -o conftest.exe -g -O2 -I/usr/include/GraphicsMagick -L/usr/lib -static-libgcc -Wl,-static conftest.cpp -lGraphicsMagick -lGraphicsMagick++  -lGraphicsMagick++ -lGraphicsMagick -ljbig -llcms -ltiff -lfreetype -ljasper -ljpeg -lpng -lwmflite -lXext -lSM -lICE -lX11 -lbz2 -lxml2 -lz -lgdi32 -lm -lpthread -lltdl -lm >&5
> /usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lxml2
> /usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lpng

* The package libxml2-devel is installed, but in my opinion is missing
the libxml2.a file:

$ ll /lib/libxml*
1122076 May 12  2010 /lib/libxml2.dll.a
    927 May 12  2010 /lib/libxml2.la

* The package libpng12-devel is installed, but there is no symlink
libpng.a -> libpng12.a. So I think GraphicsMagick should be linked
either against libpng12 or libpng14:

$ ll /lib/libpng*
294592 Aug  8  2010 /lib/libpng12.a
217944 Aug  8  2010 /lib/libpng12.dll.a

Does it sound reasonable? If yes, what is the best way to report these
two bugs?

Additional info:
libxml2-devel           2.7.7-1
libpng12-devel          1.2.44-1
libGraphicsMagick-devel 1.3.12-2
gcc4-g++                4.3.4-4

With best regards,
