I noticed the following output when configuring CVS Bison on Solaris 7:
checking for sys/wait.h... yes
checking for sys/wait.h that is POSIX.1 compatible... (cached) yes
The first item should not establish a cache for the second one,
so I installed this patch:
2003-03-12 Paul Eggert <address@hidden>
* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
AC_HEADER_SYS_WAIT.
