# Running aclocal here first (as happened for a while) caused the macros that
# libtoolize puts in the m4 directory to be newer than the aclocal.m4 file that
# aclocal creates. This meant that the next "make" cause aclocal to be run
# again. Moving aclocal to after libtoolize does not seem to cause any
# problems, and it fixes this issue.

# GNU libtool is named differently on some systems.  This code tries several
# variants like glibtoolize (MacOSX) and libtoolize1x (FreeBSD)
