[PATCH] autoconf depends on GNU M4

[This is simply a repost with PATCH in the Subject...]

Hello,

Making the previous patch for configure.in, I saw that it uses an
`ifdef([__gnu__], ..)'. I think this is needless, as autoconf depends on
GNU M4.[1]

So here comes the log and the patch is attached
[[
Remove check for GNU M4, as autoconf depends on it anyhow.

* configure.in
  define subversion_version without a check for GNU M4.
]]
