Running Emacs's 'make info' takes 6.5 seconds with texinfo 4.13, but 224 seconds with texinfo 5.0, a factor of 34 slowdown. It's now quite a wait for me to run 'make info', and this is an annoyance -- can this be sped up?
My environment is Fedora 17 x86-64 and an AMD Phenom II X4 910e processor. To reproduce the problem, grab this tarball: ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-24.2.93.tar.xz Extract it, then run the following shell commands: cd emacs-24.2.93 ./configure rm $(find . -name '*.info') make info MAKEINFO=/path/to/makeinfo-4.13/bin/makeinfo rm $(find . -name '*.info') make info MAKEINFO=/path/to/makeinfo-5.0/bin/makeinfo The first 'make' runs many times faster than the second.
