After some investigation, it seems that ffmeg hash clang (which has gcc) 
as dependency in its chain.

I would consider it a bug, although not critical.

It seems that most libraries have bash as a dependency, for example

  libmad0: recursively requires ( bash cygwin libgcc1 libiconv2 libintl8 
libncursesw10 libreadline7 libzstd1 terminfo zlib0 _windows(>=6.3) )
  libvorbis: recursively requires ( )
  flac: recursively requires ( bash cygwin libFLAC12 libgcc1 libiconv2 
libintl8 libncursesw10 libogg0 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )
  libopusfile0: recursively requires ( bash ca-certificates 
crypto-policies cygwin libffi6 libgcc1 libiconv2 libintl8 libncursesw10 
libogg0 libopus0 libp11-kit0 librea
dline7 libssl1.1 libtasn1_6 libzstd1 p11-kit p11-kit-trust terminfo 
zlib0 _windows(>=6.3) )
  libsamplerate0: recursively requires ( bash cygwin libgcc1 libiconv2 
libintl8 libncursesw10 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )
  libwavpack1: recursively requires ( bash cygwin libgcc1 libiconv2 
libintl8 libncursesw10 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )
  libcdio_paranoia2: recursively requires ( bash cygwin libcdio18 
libcdio_cdda2 libgcc1 libiconv2 libintl8 libncursesw10 libreadline7 
libzstd1 terminfo zlib0 _windows(
 >=6.3) )
  libmpcdec7: recursively requires ( bash cygwin libgcc1 libiconv2 
libintl8 libncursesw10 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )
  libcddb: recursively requires ( bash cygwin libcddb2 libcdio18 libgcc1 
libiconv2 libintl8 libncursesw10 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )
  libdiscid: recursively requires ( bash cygwin libdiscid0 libgcc1 
libiconv2 libintl8 libncursesw10 libreadline7 libzstd1 terminfo zlib0 
_windows(>=6.3) )

Again, it seems like a bug, but since so many libraries have bash as a 
dependency, could it be that cygcheck-dep incorrectly adds it?
