           Summary: llvm-gcc-4.2 configure script doesn't recognize makeinfo
                    4.11
           Product: Build scripts
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: autoconf
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: gohman at apple.com

llvm-gcc-4.2/gcc/configure.ac thinks that makeinfo vesion 4.11 is
older than version 4.4, making it too old to use. This is due to
the following code:

# See if makeinfo has been installed and is modern enough
# that we can use it.
gcc_AC_CHECK_PROG_VER(MAKEINFO, makeinfo, --version,
  [GNU texinfo.* \([0-9][0-9.]*\)],
  [4.[4-9]*])

The 4.[4-9]* doesn't match 4.11. As a result, llvm-gcc-4.2 doesn't
build the documentation.
