>Description:
The GNU preprocessor has in the past been able to append method
names after a "->". It should continue to be able to do so.
>How-To-Repeat:
When in a macro, try to concatenate some "foo->" with a macro parameter
like BAR; i.e., "foo->##BAR". Note that the preprocessor will complain,
tossing a warning and the (incorrect) text "foo-> baz" will be tossed
out. (Assuming macro parameter BAR was set to baz.) Instead, no warning
should be issued, and the text "foo->baz" should be output.
>Fix:
There doesn't seem to be a way to force the preprocessor to accept
concatenating anything with a left-hand token that ends in "->". =(
