ISO vs. AnsiC stds. Info on differences

[Vijay Tatkar]

Does anyone in this group know if there are actual areas in which the
ISO 9899-1990 std C is different from the AnsiC: X3-159.1989 std. I know
that there is a movement by the X3 Subgroup to have the former subsume
the latter (also, a statement in it clearly states that the two stds are
technically identical). I was wondering if anyone here had a differing
viewpoint [The std appears to be identical, but not a reprint of ANSI std]
Please email me and I'll post a summary to this group.
Thanx
