By telling the ACE people that the config.h file is not intended to be
installed.
If they need an installable file that contains information generated by
configure, they could use a second config header with a manually written
template that contains only the minimal set of macros to be defined (and
those should all be package-specific, e.g., have a prefix like ACE_ or
so).
Example:
AC_CONFIG_HEADERS(config.h ace_config.h)
put this in ace_config.h.in:
/* clients of the ACE library need to know whether this library was
compiled with features FOO and BAR */
#undef ACE_FEATURE_FOO
#undef ACE_FEATURE_BAR
Hope that helps.
Cheers,
Ralf
