dnl The recommended order for items in a configure.in file is
dnl     check for programs
dnl     check for libraries
dnl     check for header files
dnl     check for typedefs
dnl     check for structures
dnl     check for compiler characteristics
dnl     check for library functions
dnl     check for system services
dnl Here are some sample tests
dnl
dnl Find a C compiler (choose gcc first)
AC_PROG_CC
AC_PATH_PROG(AR,ar)
AC_PATH_PROG(RANLIB,ranlib)
dnl
dnl Find SSH.  If SSH is defined, use that instead
dnl AC_PATH_PROG(SSH,ssh)
dnl
dnl AC_PROG_MAKE_SET
PAC_PROG_MAKE
dnl
dnl     check for compiler characteristics
AC_C_CONST
dnl
dnl Look for Standard headers
AC_HEADER_STDC
dnl Check for a specific header
AC_CHECK_HEADERS(string.h sys/time.h unistd.h sys/types.h stdlib.h errno.h)
dnl
dnl Setup other replaceable values
MPILIBNAME=mpich
AC_SUBST(MPILIBNAME)

AC_SUBST(master_top_srcdir)

dnl Configure any subdirectories.  Note that config.status will *not* 
dnl reexecute these!
dnl Export any important variables first:
export AR
export RANLIB
export MPILIBNAME
export CC
