This is a modified copy of the libassuan library.  Don't modify it,
but instead modify the original Assuan library and merge the changes
back into this copy.

The changes to the original libassuan, that have to preserved when
updating this directory, are:

* Makefile.am
** Build the library with libtool as a convenience library, which can
   be linked into the shared library GPGME.
** Do not install the library or the header file.
** Define -D_ASSUAN_IN_GPGME_BUILD_ASSUAN to wrap some POSIX functions
   with ATH replacements.

* assuan.h
** Define _ASSUAN_IN_GPGME to enable GPGME specific code.
** Put all exported Assuan functions in the _gpgme namespace.
** Also wrap all system functions that are wrapped by GNU Pth to
   _gpgme wrappers.

* assuan-io.c
** Don't try to support GNU Pth here.
