The MSVC binaries are compiled without getopt support. See the notice for fluidsynth -h

FluidSynth runtime version 2.4.5

Usage:
  fluidsynth [options] [soundfonts] [midifiles]

Note:
  This version of fluidsynth was compiled without getopt support.
  Thus, the long options are not supported.

Therefore, this is not a bug, it's a feature request for getting getopt support for MSVC builds.

[pedrolcl]

There is a getopt-win32 package in https://vcpkg.io/ but it is not a blind drop-in. It will need some tweaking on the build system.

Another alternative would be getopt_port (BSD licensed).
