Yes, I think the differences are simple - I had the Fedora packages
installed through Debian alien

export DEB_BUILD_GNU_TYPE:=$(shell dpkg-architecture
-qDEB_BUILD_GNU_TYPE)
is not in Fedora
export DEB_HOST_GNU_TYPE:="i586-pc-mingw32"
HOST_TOOL_PREFIX:=i586-mingw32msvc
are different in Fedora

One could use simply use: which fedora-one dpkg-architecture
as a test. For me that command returns /usr/bin/dpkg-architecture
and /usr/bin/dpkg-architecture returns i486-linux-gnu .
Depending on the outcome one could adjust all three.

As to the stuck linker bug: I am just working on it. Something seems
fishy with the macros at the end of include/ptlib/plugin.h . Possibly
they are only for MSVC  and we should use the "USE_GCC" mechanism for
__MINGW32__. Using slightly changed ones in a separate source file to
Ekiga gives some hope:
i586-mingw32msvc-nm ekiga/src/.libs/ekiga.exe | grep WindowsMultimedia
00a283e0 d .data
$_ZGVZN52PPlugin_PSoundChannel_WindowsMultimedia_RegistrationC1EP14PPluginManagerE7factory
00a29e50 d .data
$_ZZN52PPlugin_PSoundChannel_WindowsMultimedia_RegistrationC1EP14PPluginManagerE7factory
008bd37c t .text
$_ZN52PPlugin_PSoundChannel_WindowsMultimedia_RegistrationC1EP14PPluginManager
00afb398 B
_PPlugin_PSoundChannel_WindowsMultimedia_Registration_Instance
00a24a30 D
....
more for PVideoInputDevice_DirectShow and
VideoInputDevice_VideoForWindows
I did not get that with the original Ptlib macros, it was zero output.
Give me a bit more time.
