Bug in Guile

Bug in Guile

[Dr William Bland]

I have found what appears to be a bug in Guile's reading of large
integers.  If I try the expression in the email included below in Guile
1.4, I get +#.#.  This has also been tried on Guile 1.6.2 and that gives
an error (see the email below).

Best wishes,
		Bill.

Hmm.  And 1.7 gives us:

I'll add it to my list of things to look in to.  Now with GMP, we can
