Subject: problem with '^' as first char in BRE for expr

I use bash and fileutils from the latest distribution
on Windows-NT 4.0 SP5.

expr 'abc' : '^a\(.\)c$'
delivers:
expr: warning: unportable BRE: `^a\(.\)c$': using `^' as the first
character
of the basic regular expression is not portable; it is being ignored

Question:
I think the character '^' in a BRE is not irrelevant,
why is it ignored?

Regards
Helmut Dipper
