aclocal.m4 is generating a wrong configure file

[Pedro Kröger]

this expression in aclocal.m4, around line 694

    # use absolute path.
    if [ "$srcdir" != "." ];  then 
        srcdir=$(cd $srcdir;  pwd)
    fi

is generating this code (note there is no brackets) in configure, around
line 1494:

    # use absolute path.
    if  "$srcdir" != "." ;  then
        srcdir=$(cd $srcdir;  pwd)
    fi

which, naturally, raises an error.

I'm using M4 1.4.3 and autoconf 2.59.

Any ideas?
