config.h must always be the first header becuase it controls features
provided by the system headers.  The latter SHOULD prepend application
specific headers to ease debugging.

The tricky part is the GPG_ERR_SOURCE which has a default unless set in
another way.  In general not a problem but sometimes things get messed
up.

Pretty easy: This requires linking to libintl even for tools which have
no need for it.

On Linux this is not a problem as long as the amount of mlocked memory
is small enough.  On other OSes you may want to suid the application to
take advantage of mlocked memory.

The gcry_check_version is important and chould be done explicit.
