 Yes, gcc 3.2.1 still generates paths containing bin/../lib
 
 mkdir /tmp/c
 ln -s /umr/s/gcc321/install/redhat71/lib /tmp/c/lib
 ln -s /umr/s/gcc321/install/redhat71/bin /tmp/c/bin
 /tmp/c/bin/gcc -print-prog-name=3Dld
 
 /tmp/c/bin/../lib/gcc-lib/i686-pc-linux-gnu/3.2.1/../../../../i686-pc-li
 nux-gnu/bin/ld
 
 
 There's nothing _wrong_ with that path, but I figured that having gcc
 generate a path without the ..'s would help the situation some. (The
 bin/../lib is where the problem occurs if autoconf uses non-intelligent
 handling of .. in paths containing symlinked dirs.)
 
 /tmp/c/bin/.. !=3D /tmp/c if /tmp/c/bin is a symlink.=20
 
 As people are more likely to install updated O/S with new gcc, fixing
 here is more likely to have a benefical impact than getting everyone to
 move to new autoconf, especially for older products.=20
