You shouldn't. You have 2 reasonable choices:
1) Invoke AC_HEADER_ASSERT in configure.ac, giving the
user the option to pass --disable-assert to configure.
2) Do nothing, and allow the user to pass CPPFLAGS=-DNDEBUG
to configure.
You might choose to set -DNDEBUG in AM_CPPFLAGS, but
it really is best to let the user do it. If you want
to ensure that assertions are disabled in binary
builds, then add the appropriate argument to the
configure invocation in the build file (eg, debian/rules
or a spec file).
