on Windows, with mingw, libbfd may depend on gettext (libintl, more
precisely). I would like to do something like:
AC_CHECK_LIB([bfd], [bfd_openr],
[
have_bfd="yes"
bfd_libs="-lbfd"
],
[have_bfd="no"])
if test "x$have_bfd" = "xno" ; then
AC_CHECK_LIB([bfd], [bfd_openr],
[bfd_libs="-lbfd -lintl"],
[AC_MSG_ERROR([the symbol bfd_openr can not be found])],
[-lintl])
fi
On my system, binutils is sufficiently recent, hence libbfd depends on
libintl. So the first test fails. But with the cache feature, the second test
also fails.
