Killing @ symbols in exported functions

[Al]

When I compile dlls (using cygwin on windows) the exported functions names
have an @ and a number appended to them. I cant have this.

It can be rectified when using gcc by passing the --kill-at flag to the
linker, but how to do this via libtool and how to do it in a portable way? I
mean how should I write my .am files to have libtool take care of this for
me regardless of the linker being used.

Thanks.
