I have looked through your logs. It appears that you have vfw.h but in a
version too outdated for ptlib. If you work on a debian based system you
may try to install
http://wwwuser.gwdg.de/~mrickma/ekiga/mingwrt/mingw32-runtime_3.15-1_all.deb .
I know Fedora has it as well but cannot find it at the moment. Otherwise
you may consider to go to mingw.org, get the latest Win32 headers and
poke them into your system.
