gcc build on FC18 and automake 1.11

[Nenad Vukicevic]

The latest Fedora Core 18 comes with automake 1.12.1 and perl 5.16.2. I 
installed and tried to use automake 1.11.1 for one of the GCC libraries, 
but got a warning from aclocal:

main::scan_file() called too early to check prototype at 
/usr/local/bin/aclocal line 617.

The latest 1.11.6 has the same issue, but automake 1.12.1 fixed that 
warning by having subroutine prototypes early in the code.

What would be the right way to go about this? Just put up with the warning?
