Hi Paul,

I don't think we should put this into the docs, because that can change
at any time.  Maybe into porting_to.html, though (where I have only
mentioned this as a general issue with linear congruential generators,
without mentioning specific options. Current text can be seen at
https://gcc.gnu.org/gcc-13/porting_to.html ).

Hm....

Best regards

	Thomas
