Documentation flaw in autoconf

[Michaël Grünewald]

Short: path to directories may be relative or absolute, section 3.3.1 of 
the documentation ignores this.

Dear GNU folks,

Autconf will substitute in Makefile's templates many ``Preset Output 
Variables''. Some values of these variables represents path to 
directories in the file system. The documentation (section 3.3.1) does 
not tell whether these paths are absolute or relative, or if this 
characteristic is unspecified. The documentation should be explicit 
about this issue.

By the way, it could be useful to have some variables representing paths 
to directories and being guaranteed to be absolute. (I think especially 
to top_srcdir).

Here is the version of autoconf I use:

 > autoconf --version
 autoconf (GNU Autoconf) 2.61

P.S.: I just noticed that Autoconf's documentation refers to 
address@hidden' whereas address@hidden' shall 
now be used.
