+ and BeOS (without thread support yet)

+ added new GetCPUCount() and SetConcurrency() functions (useful under Solaris
+ only so far)
+- wxDir class for enumerating files in a directory
+- wxLog functions are now (more) MT-safe

+- buffer overflows in wxString and wxLog classes fixed (if snprintf() function
+ is available)
