Hi,
This piece of code in configure.ac of gdbserver does not work as
intended, since gcc only gives an warning if it does not accept
-rdynamic.
LDFLAGS="$LDFLAGS -rdynamic"
AC_TRY_LINK([], [], [RDYNAMIC=-rdynamic], [RDYNAMIC=])
AC_SUBST(RDYNAMIC)
Is this a problem? For one thing, usually dejagnu reports gcc warnings
as fatal; the test would fail if the option generated a warning. For
another, the option should be used unless it causes gcc to fail;
using it even when GCC doesn't support it should be harmless.
