i hope there is someone still out there can help me with this........if so, hello.
readline will not install on opensolaris 2008.05 due to configure errors.
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
I looked at the autoconf documentation and it seems that AC_CHECK_HEADERS are messing up.
The autoconf documentation suggest that AC_CHECK_HEADERS should have 4 parameters - in the readline configure.in it has 1.
