Hi.  Actually, I cannot find a license header in libtasn1-config.in, so
I'm equally confused.

Normally build infrastructure stuff is GPLv3, so using that would be
close at hand.  Alternatively, the all-permissive license used for other
autoconf-related files may be used.  I noticed that libgcrypt uses it.

However, I would prefer to get rid of the *-config scripts.  The idea
behind *-config scripts is against the normal autoconf-approach to test
for features, and works poorly in corner cases.  Even if some users
prefers that model rather than the normal autoconf-approach, libtasn1
supports pkg-config.  Pkg-config is at least widely used, and the M4
code for it is likely more correct than libtasn1.m4.  People have
probably adapted pkg-config for some corner cases before us.

So let me propose that we remove libtasn1-config and libtasn1.m4 from
libtasn1.  Instead, we recommend developers to use the normal
autoconf-machinery to test for libraries, or if they don't like that,
that they use pkg-config.
