dnl we also have to check whether we should use statvfs_t (works under
dnl Solaris 8, doesn't work under Solaris 7) or "struct statvfs" (vice
dnl versa) as the argument for statvfs in 64 bit off_t mode (in 32 bit
dnl mode both work fine)
dnl
dnl for this check C++ compiler has to be used as passing incompatible
dnl pointers is just a warning and not an error in C
