Support building C++ files with MSVC
Made appropriate changes to be able to successfully
build C++ files using a Visual C++ build on Windows.
Based on an earlier patch by Kyle Schwarz.
Comments:
-- compat/w32pthreads.h: Made appropriate changes to w32pthreads.h to
get it to build when it is being included in a C++ file and built
with Visual C++. This is mostly a copy of Kyle Schwarz's patch as
described above.
-- configure:
a) Now calling set_ccvars CXX to cause the various CXX_ variables to
be setup properly. For example, with MSVC (Microsoft Visual C++),
this causes CXX_O to be set to -Fo$@ instead of using the default
value. The default value does not work with Visual C++. This
change will also have the impact of correcting CXX_O (and possibly
CXX_C) for other compilers, although this is really only relevant
for the Intel compiler, in addition to MSVC.
b) Now using cl for the C++ compiler for the MSVC toolchain. This is
currently only relevant for building the
Blackmagic/Decklink-related files under avdevice.
