aclocal.m4 was generated with wrong autom4te. This patch should work.

Thanks, I checked in the regenerated files after a bootstrap, and:

I don't think "-I libltdl" is needed.

Perhaps you could share the exact versions and command lines you used to 
generate aclocal.m4.

Noting the procedure in the HACKING file would be helpful as well.

Thanks

You just need to do

# cd libjava
# rm aclocal.m4
# make aclocal.m4

and make sure that automake 1.9.6/autoconf 2.59 are really used. The
actual command is

# aclocal -I . -I .. -I ../config

Except that aclocal.m4 lives in the source directory.

I am using

   cd libjava &&
   rm -f aclocal.m4 &&
   ACFLAGS=$(grep "^ACLOCAL_AMFLAGS" Makefile.in | sed -e "s/ACLOCAL_AMFLAGS[ \t ]*=//") && 
   aclocal-1.9 $ACFLAGS &&
   rm -f configure &&
   autoconf-2.59 &&
   rm -fr autom4te.cache

to simplify the step.
