Documentation for getpwuid_r from POSIX:
  http://pubs.opengroup.org/onlinepubs/009695399/functions/getpwuid.html
and for LINUX, which contains a getpwuid_r example:
  http://www.kernel.org/doc/man-pages/online/pages/man3/getpwnam.3.html

Seems so - but fortunately, the exact version requirements do not seem to be
that strict: using a -static-ally linked test case (from kernel.org, cf. link),
linked on a GLIBC 2.11.3 system worked on a system with glibc-2.5-49.el5_5.2.
