In GNUnet configure.ac, there is the fragment:
# test for libunistring
gl_LIBUNISTRING
AS_IF([test "x$gl_libunistring_hexversion" = "x" || test
"$gl_libunistring_hexversion" -le 2305],
[AC_MSG_ERROR([GNUnet requires libunistring >= 0.9.1.1])])
that uses the var ‘gl_libunistring_hexversion’ which is
undocumented (IIUC). OTOH, var ‘LIBUNISTRING_VERSION’ is
indeed documented, and has value something like "0.9.10".
Is there any Autoconf support for comparing these two version
strings: "0.9.1.1" and "0.9.10"?
