How many of these platforms you use are POSIX-compliant?  This 
information came from the POSIX web site (NOT THE DIGITAL/COMPAQ/HP/... 
WEBSITE).  Sysconf(_SC_GETPW_R_SIZE_MAX)  is supported by Solaris 2.5, 
SCO UNIX (circa 1999!),  Digital UNIX/Compaq Tru64 UNIX, FreeBSD,  AIX, 
HP-UX, and probably many more.

Maybe the non-compliant platforms should be catered for as "legacy" with 
support code in the "ports" area, and those that do adhere to open 
standards can be accommodated without breaking existing production 
applications.

Thanks
Peter
