Then I think the error message is misleading.  Perhaps it should
say that there is no default constructor. i.e. "no matching call for
A::A()"
not "no matching call for A::A(int)"

BTW: the parameter type mentioned in this error message is always
the type of the last parameter in the constructor I am trying to invoke.
i.e. if 'b' was a bool, and I was passing '(1,false)' as parameters then
I get "no matching call for A::A(bool)".  Clearly there is some kind of
error!

BTW2: gcc-2.7.2.1 must be wrong because it compiles this fine.
And it does what I expect it to!
