After discussing on IRC, this patch is not needed: the current version
of libtasn1, 4.8, has the gcc-warnings option disabled by default, so
it does not add -Werror.

Apparently, the problem starts with version 4.9, which Gustavo was
about to submit as a security fix. In this case --disable-gcc-warnings
should be used.

Best regards,

Thomas
