When building FFMPEG in the MSYS environment under Windows, one
must not use forward slashes ('/') for command-line options. It
appears that the MSYS shell interprets these as absolute paths and
then automatically rewrites them into equivalent Windows paths. For
example, the '/nologo' switch below gets rewritten to something like
'C:/Program Files/Git/nologo', and this obviously breaks the build.
Thankfully, most M$ tools accept dashes ('-') as well.
