Yes, you are probably using the standalone distribution of MinGW
and/or the companion MSYS tools.  These have no support for long
command lines via @responsefiles.

To avoid this problem, use the version of MinGW that is part of the
Cygwin distribution.  This is briefly mentioned in the README.win32
file in the OCaml distribution.
