Hello Frank, Thanks for the bug report.

The Autoconf version that matters for an issue with a package that uses Autoconf is the one that readline-5.0 was configured with. You can find it out by typing ../../src/readline-5.0/configure --version in the directory you built in. But anyway, what you have found is not an Autoconf bug, but a small buglet in the configure.ac (or configure.in) script of readline-5.0. > # uname -a > SunOS apogee6 5.10 Generic_118833-24 sun4u sparc SUNW,Ultra-80 [...] > checking sys/ptem.h usability... no > checking sys/ptem.h presence... yes > configure: WARNING: sys/ptem.h: present but cannot be compiled > configure: WARNING: sys/ptem.h: check for missing prerequisite headers? > configure: WARNING: sys/ptem.h: proceeding with the preprocessor's result On your system, the header sys/stream.h is a prerequisite of sys/ptem.h. this is documented here for Solaris 8: http://www.gnu.org/software/autoconf/manual/html_node/Header-Portability.html#index-g_t_0040file_007bsys_002fptem_002eh_007d-506 and the way to fix this is documented here: http://www.gnu.org/software/autoconf/manual/html_node/Present-But-Cannot-Be-Compiled.html The author of readline should use a test like this for sys/ptem.h: AC_CHECK_HEADERS([sys/ptem.h], [], [], [AC_INCLUDES_DEFAULT #ifdef HAVE_SYS_STREAM_H # include <sys/stream.h> #endif ]) Please forward this to the readline developer, if a newer version of readline doesn't have this issue fixed already. Cheers, Ralf
