Can't build Pan

I've updated my building environment (or whatever you may call it) 
- MinGW, Gmime, GTK+ etc., and now I can't build Pan.
I get this:

if g++ -DHAVE_CONFIG_H -I. -I. -I../..  -I../.. -IC:/msys/1.0/opt/gmime/include/gmime-2.0 -IC:/msys/1.0/opt/gtk/include/glib-2.0 -IC:/msys/1.0/opt/gtk/lib/glib-2.0/include   -IC:/msys/1.0/opt/gtk/include/glib-2.0 -IC:/msys/1.0/opt/gtk/lib/glib-2.0/include   -IC:/msys/1.0/opt/pcre/include   -I/c/mingw/include -I/opt/gtk/include -I/opt/pcre/include -I/opt/gmime/include -DWIN32_LEAN_AND_MEAN  -O -Wall -ggdb3 -mms-bitfields -mwin32 -mwindows -MT progress.o -MD -MP -MF ".deps/progress.Tpo" -c -o progress.o progress.cc; \
then mv -f ".deps/progress.Tpo" ".deps/progress.Po"; else rm -f ".deps/progress.Tpo"; exit 1; fi
progress.cc: In member function `void pan::Progress::set_status_va(const char*, ...)':

Before I start checking all possible combinations of software in order to 
get rid of the problem, maybe someone has an idea how to fix it?
