System: OpenBSD underhill.hhhh.org 3.7 UNDERHILL#0 i386
tools/compat/configure.ac passes four parameters to AC_CHECK_FUNCS(), but
the macro only takes three. The fourth argument is apparently intended to
go into the test file's prologue (a la AC_LANG_PROGRAM). There doesn't
seem to be a way to pass that information in to AC_CHECK_FUNC[S] though.
The result is that configure incorrectly decides that my host system
does not have most of the functions it's testing (the byte-order functions
and some string functions such as strmode()). This, in turn, causes
the tools build to fail because of header-file clashes.
You can verify that the test file in the configure script does not
include the #include line from the autoconf script.
Build from CVS tag netbsd-3 on OpenBSD-3.7.
Must apply patch from PR#31077 first if building from the netbsd-3 branch.
Can hack around it by hardcoding the values in configure.ac.
