../../src/visibility.c:498:3: warning: implicit declaration of function `_gcry_mpi_ec_new' [-Wimplicit-function-declaration]

[Peter Wu]

Hi Werner,

While building the latest git master (libgcrypt-1.5.0-283-g738177e), I got a 
warning about an implicit declaration of a function. As far as I can see, it 
was caused by:

    commit 64a7d347847d606eb5f4c156e24ba060271b8f6b
    Author: Werner Koch <wk at gnupg.org>
    Date:   Sat Sep 7 10:06:46 2013 +0200
    
        ecc: Refactor low-level access functions.

The declaration was previously done in src/mpi.h which is included by 
src/visibility.c, but now ec-context.h is not included by any visibility-
related file.

Regards,
Peter
