`-h` needs to be removed before 9.4 according to error
In RtsFlags.c
on both master
and ghc-9.4
you will find the following line:
errorBelch("-h is deprecated and will be removed in the next release (9.4),\nuse -hT instead.");
We should ensure we don't forget to remove this option before 9.4 is released.
