Version numbers for libtasn1.h
Description of problem:
It's not easy to check for a certain version of libtasn1.h since the only version information is
#define ASN1_VERSION "4.13"
How to check for major/minor via C preprocessor (
#if ...) ?
Version of libtasn1 used:
Use the same standards mechanism as other libraries do, e.g. gnutls.
