Qt 6.2.2 MinGW 9.0.0 does not deploy gfortran

As of v6.2.2 with MinGW move to 9.0.0 *gfortran *compiler are no longer supplied.

Refer to Forum posts at: https://forum.qt.io/topic/133616/qt-6-2-2-and-mingw-9-0-0-does-not-deliver-a-fortran-compiler* re necessity for the *gfortran compiler to still be available. Summarised, many libraries used in the curring-edge software in the communications, aerospace and high-technology research world still use Fortran and are most efficiently dealt with via Fortran.

It is exceptionally difficult to work around this issue (again see forum posts). as MinGW compilers and tools are built with posix and seh options . Drop-in replacements for the 11.2 MinGW stream are not available anywhere to overcome issues.

Evidence (rom a current deploy):

Qt needs to deliver this compiler standard and/or make an Installer/Maintenance Tool package available to deploy this MinGW compiler tool/component.
