apache dll name mangling

[Surendra Singhi <ef...@netscape.net>]

Hello,
  I am trying to write a ffi interface to apache httpd windows dlls, and I ran
into the issue of name mangling.
I can solve this problem for the particular version of dlls which I am using
but it is not a generic/portable solution for different platforms.

In particular I would like to quote Roger Corman (the main person behind
Corman Lisp) on the topic of name mangling and automatically taking care of it
in ffi interfaces (back in 2003), aka. "decoration":

>You could try to make it easier by doing his automatically, but you don't

>The Microsoft C++ compiler automatically does the name mangling unless you tell it otherwise.
>This is to catch problems (incorrect declarations) at link time rather than run time.

>Microsoft does this for all their system DLLs. The names are not mangled.


So, I will request that future release of apache, should try to avoid dlls
with mangled names.

Any comments?

Thanks for your consideration.
