No, I have no experience with --enable-checking. I had to look up the
doc:

<< 
--enable-checking 
--enable-checking=list 
When you specify this option, the compiler is built to perform
checking of tree node types when referencing fields of that node, and
some other internal consistency checks. This does not change the
generated code, but adds error checking within the compiler. This will
slow down the compiler and may only work properly if you are building
the compiler with GCC. This is on by default when building from CVS or
snapshots, but off for releases. [...]

I build gcc from CVS sources, therefor the tested gcc always had
checking enabled.  I don't see how that has any influence on the ACATS
results, though, as it does not change the generated code.
