Subject: Remove check for `const` keyword in configure.ac
X-Git-Tag: 2.40.1~2^2~1^2^2~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=741e528276cb2e637c0fcc2e19682a4dffdbddbf;p=graphviz

Remove check for `const` keyword in configure.ac

The macro `AC_C_CONST` checks whether the used C compiler supports
the keyword `const` and defines it accordingly. But as stated in
the autoconf documentation, this macro is becomming obsolete as
current C compilers `cost`. Checking is therefore no longer required.
