The gst...c/.h files are found in the gst/elements directory, while mman.c/.h/.inl files are found only in the win32 directory, and without the usual GStreamer's copyright, or the LGPL boilerplate.

The reason I ask is that compling using a cygwin make fails at the point when gstmultifilesrc.o is being linked because 'MADV_SEQUENTIAL' is undelared in the gst_multifilesrc_open_file function which has a implicit declaration of function 'madvise'.

It seems that similar code in gstfilesrc.c is bypassed due to a '#ifdef MADV_SEQUENTIAL', which is missing in gstmultifilesrc.c, which leads me to think that if gstmultifilesrc.c were added to the gstelements solution, it would fail in MSVC as well ...

I have no idea what this madvise code in the gst source is doing or how "mman" code is being used.
