Hi there,
I have switched to the latest autoconf snapshot (2.52e, cvs-updated today) and have tried hard to follow all the instructions for the upgrade. I believe I am no longer using any deprecated feature, but I get $ autoreconf configure.ac:21: warning: do not use m4_patsubst: use patsubst or m4_bpatsubst configure.ac:312: warning: do not use m4_regexp: use regexp or m4_bregexp autoheader: `config.h.in' is unchanged Line 21 in configure.ac reads AM_CONFIG_HEADER(config.h) while line 312 is the last one in the following invocation of AC_OUTPUT: AC_OUTPUT(Makefile src/Makefile src/BitSet/Makefile src/Integer/Makefile tests/Makefile m4/Makefile doc/Makefile doc/user-browse.doxyconf-latex doc/devref-browse.doxyconf-latex doc/user-print.doxyconf-latex doc/devref-print.doxyconf-latex doc/user.doxyconf-html doc/devref.doxyconf-html ppl.lsm ppl.spec) What am I missing?
