On Solaris 2.8 I'm running autoconf-2.52, automake-1.4l, and libtool-1.4b, but am getting the following message when I run autoheader [196.artemis.mep] autoheader NONE:0: /swl/SunOS-5.8/bin/m4: `m4_symbols' from frozen file not found in builtin table! NONE:0: /swl/SunOS-5.8/bin/m4: `syncoutput' from frozen file not found in builtin table! NONE:0: /swl/SunOS-5.8/bin/m4: `changesyntax' from frozen file not found in builtin table! What am I doing wrong? Thanks in advance, - Ted
