[patch] Missing casts in gcrypt.h

[Andreas Metzler]

Hej,
this is http://bugs.debian.org/362636 reported by Erik Meusel.
| when I try to use GCRY_THREAD_OPTION_PTHREAD_IMPL from
| /usr/include/gcrypt.h with g++, there are compilation problems due to
| missing casts from void * to pthread_mutex_t * and back. The following
| version works for me quite well:

suggested simple patch (by Erik) is attached. This applies to both
1.2.2 and svn trunk.
  thanks, cu andreas
