dnl First, we'll test for C-specific features.
AC_LANG_C

dnl Checks for libraries.
libdl=
libm=
AC_CHECK_LIB(m, sin, libm=-lm)
AC_SUBST(libm)

dnl Checks for header files.
AC_HEADER_STDC
AC_CHECK_HEADERS(malloc.h alloca.h unistd.h io.h minmax.h sys/types.h string.h regex.h)

dnl Checks for typedefs, structures, and compiler characteristics.

dnl Checks for library functions.

dnl Now we can test some C++-specific features.
