Hi,

A few suggestions:
Related to "#pragma interface" and gang, could you submit a bug report
to the gcc folks ? As far as ddd is concerned, you could write an autoconf
test that makes sure that "#pragma ..." does not create a link failure
and patch properly the ddd source code. "#ifndef __CYWIN__" all over
the ddd source code is not acceptable IMO.
Related to the libtool problem, you should get the ddd source from the
CVS repository and use "./CVSMake" directly under cygwin using recent
version of the autotools. It may uncover some problems in configure.ac
and friends. Please report (and possibly fix) them to ddd@gnu.org.

Regards,
