Personally I compile router, mailbox and (for no good reason) smtpserver
with a replacement getpwnam/getpwuid.  My custom library does take care
of `special' uids like `nobody' etc.  As long as the same custom library
is used with POP and FTP that are not aware of it, it (the library)
have to supply `special' uids anyway.  Thus, I do not see any good point
in special handling in the application program.  What *I* need is a
way to include context like

	-L/usr/abs/lib -labs_pwd -labs_access -labs_mail

to the linker command line, that's all.  Currently, I am doing this with
a small sed script run on Makefiles.


OFFTOPIC: actually, this replacement library is a part of the system
wide customer authentication and accounting database; it uses Oracle
as backend, has `agent daemons' running on all involved machines that
are connected to the backend daemon over SSL and responding to local
queries over UNIX domain sockets.  Although complicated, the system
seems to work ;), getpwnam type query takes 70+ ms right now.
