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
** Preserve the block between "Begin/End GPGME specific modifications".
In particular make sure that
#define _ASSUAN_EXT_SYM_PREFIX _gpgme_
#define _ASSUAN_NO_PTH
#define _ASSUAN_NO_FIXED_SIGNALS
#define _ASSUAN_USE_DOUBLE_FORK
are defined. This puts all exported Assuan functions in the _gpgme
namespace. It also wraps all system functions that are wrapped by
GNU Pth to _gpgme wrappers.
* assuan-io-pth.c
We don't need this file as GPGME doesn't use sendmsg and recvmsg.
If it would, we would need to pick up the W32 implementation.
* assuan-io.c
** _assuan_simple_read() and _assuan_simple_write() must always use
read()/write() (which actually translates to _gpgme_io_read() and
_gpgme_io_write()). _assuan_close must always() use close() (which
translates to _gpgme_io_close()).
