(Sorry about the lengthy quoting, but in case it is relevant to some
TeX wizard I'll leave it in.)

Inspired by a TeX message I saw earlier today to be like Hercule
Poirot, I discovered that if I comment out

\let\ProvidesFile\ProvidesPackage

in miniltx.tex, then everything seems to work fine.

I don't know the full ramifications of commenting this out, can anyone
give an informed opinion?

Thanks.
