We've already tried hard to make AC_C_RESTRICT pick a value that will work for both C and C++ compilers, as long as both compilers are from the same vendor. If we can't come up with anything better than __cplusplus, then I guess that will have to do, but is there any way we can detect this at configure time while probing only one of the two compilers? Also, we already have a __SUNPRO_CC-specific workaround for two different definitions of restrict for the C/C++ pair of the Sunpro compiler suite - is there a another preprocessor macro we can reliably use to identify this Tru64 vendor compiler pair? -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
