Subject: GtkExtra on win32


Well I went ahead and compiled the wole thing as a dll, I am
attaching the makefile if you are interested. However 3 files do not
compile (using the mingw32 compiler). The files are
gtkiconfilesel.c gtkdirtree.c gtkfilelist.c

the first 2 have some conflicts, redifining some things (that was my
earlier message), the 3rd gtkfilelist includes fnmatch.h which is specific
to glibc. There is word however on the mingw32 list that a glibc port is
in the works (which may solve some other problems). 

After I compiled the dll, I tried the test programs
testgtksheet and testgtkfont got as far as the console windows and then
printed a lot of Gtk-Critcal invalid cast from (NULL) pointer to
'GtkEntry'
testgtkplot worked sortof, but not well and crashed easily. Is this due
to the gtklayout problem? anyway here is my makefileand if I get some more
time I may actually start to do some debugging.
