I'm making a hack which require a macro to generate goto labels (I can of
course provide the label as an argument to the macro, but that significantly
reduces the maintainability of the resulting code).
My idea was to do like this:
label ## __LINE__:
but then I just get
label__LINE__:
after the preprocessor has done its work, and I would like to have
label897:
if the line number happened to be 897.
Is it possible with this way, or other, to generate unique goto labels with
the preprocessor?
Please answer to me directly, since I'm currently not on the list.
