# $NetBSD: configure.ac,v 1.6 2003/07/26 20:24:01 salo Exp $
Break out make(1) bootstrap config into an autoconf-based mechanism that generates a shell script. Check for existence of POSIX regex, and make sure an appropriate library is pulled in for it as needed.

AC_CONFIG_FILES(buildmake.sh)
Check for the location of sh on the path, and use that to construct the value for _PATH_DEFSHELLDIR. In theory, _PATH_DEFSHELLDIR will also be used to find csh, but ".SHELL csh" shouldn't be used anywhere in our source tree, and this make shouldn't be used for other things. This should cause nbmake to use the right shell for most purposes when cross-compiling from Solaris.

AC_PATH_PROG(BSHELL, sh)
if test x"$BSHELL" = x; then
AC_MSG_ERROR([sh must be somewhere on \$PATH])
fi
Define _PATH_BSHELL to the first "sh" on the PATH when bootstrapping nbmake. This should remove our dependency on a nobbled /bin/sh on Solaris.

# regcomp() and regexec() are also names of functions in the old V8
# regexp package. To avoid them, we need to find out who has regfree().
dnl # Cygwin: We *MUST* look at -lregex *before* the "no libs" condition.
dnl # Thus AC_CHECK_LIB(regex...) comes first, and AC_SEARCHLIBS next.
AC_CHECK_LIB(regex, regfree)
AC_SEARCH_LIBS(regfree, rx posix)
Make util.c replacement functions use autoconf conditionals to probe what is Really available in the host OS.
