[FFmpeg-user] errors relating to libgcrypt

[hydra3333]

Hello, 2 things. 

1 Apparently ffmpeg can be built with --enable-gcrypt so I thought I'd give
it a try.
libgpg-error is a dependency of libgcrypt.
One or both of two recent commits in
https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgpg-error.git;a=summary 
seems to cause an error building libgcrypt
https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=summary 
Does anyone else experience this ?
I am unsure how to report that, any ideas ?

2 Anyway, building with a prior libgpg-error commit works, however when
ffmpeg is then built (cross-compiled) with --enable-gcrypt then the
configure aborts saying that ffmpeg didn't detect gcrypt.

What am I doing wrong ?
