DIfferences between 2.13 and 2.52

[Michael Sabielny]

Hi folks,

after updating from SuSE Linux 7.2 to 7.3 we found out that the version 
change of autoconf now produces some strage error messages while running on 
our acconfig.h, acinclude.m4, aclocal.h skeleton.

With autoconf version 2.13 it all works fine, but with version 2.52 it throws 
an error like this:

address@hidden:~/xvisqt> autoconf
./aclocal.m4:549: error: m4_defn: undefined macro: _m4_divert_diversion
aclang.m4:173: AC_LANG_RESTORE is expanded from...
./aclocal.m4:549: the top level
address@hidden:~/xvisqt>

What is desribed as xvisqt is a qt-program build from kdevelop. The 
configure/makefile.in skeleton was autogenerated from that IDE, too.

In line 549 of aclocal.m4 one can find exactly this:
 
AC_LANG_RESTORE
])

Any ideas?
