OK, thanks! The task now becomes how do we distinguish between systems 
with and without strerror_r?

Do you know if <cstring> and/or <string.h> come with Solaris or with the 
Sun compiler or perhaps separate from either?

Boost's 1.34.0 regression test config_info is reporting:

   Sun compiler version 0x580
     ...
     sun                                     =1
     __SUNPRO_CC                             =0x580
     __sun                                   =1

If the header comes with the compiler, perhaps we can use the 
__SUNPRO_CC value to discriminate.

Thanks,
