Inline's make test was croaking in
 Inline::check_config_file

My tests seem to indicate that compiling the line that checks for
   defined %main::Inline::Config::
caused the symbol to exist.    (see how the test case file q.t
causes %main::Inline::Config:: to be added to the symbol
table after the eval.
(This also shows that the "exists" check
  doesn't modify the symbol table, and
  it does catch when the symbol is in the table)

$ perl q.t
defined at (eval 1) line 1.
exists 2 at q.t line 3.
$ cat q.t
warn "exists 1" if exists $main::Inline::{'Config::'};
eval " warn 'defined' if defined %main::Inline::Config::;";
warn "exists 2" if exists $main::Inline::{'Config::'};
