[FFmpeg-devel] [PATCH] configure: force -nologo- when detecting MSVC

[Steve Lhomme]

The -nologo- option is the inverse of -nologo, reenabling printing the
"logo" version header. This is useful if the compiler actually is a
wrapper that forces -nologo.

--
this can be useful if you use a wrapper than forces -nologo by default
