The function in question, strdup, has never been part of
standard C/C++, and its presence in <string.h> is forbidden by

So much for standards compliance.
strdup is a POSIX Standard (IEEE Std 1003.1-2001) function.
The must have removed it since then, then, since in the on-line
version of IEEE Std 1003.1-2004, it is documented as an "X/Open
System Interfaces Extension"---standard Unix, but not Posix.
As a Unix/Linux developer working with a cross-platform
codebase (Windows, AIX, Solaris, Linux), the POSIX functions
are important to me.
Linux isn't really Posix compliant (and doesn't claim to be),
although it does support much of both Posix and the X/Open
System extensions. Windows from what I've seen, has a Posix
compatible layer, but it is for all practical purposes
unusable---it's just there to be able to claim Posix compliance
when that is required. And Solaris isn't really Posix compliant
by default, either; you need to use special options with the
compiler.
Posix helps, but it isn't really a guarantee. (In this, it's no
different than the C++ standard, which is ignored by most of the
major vendors whenever they find it convenient.)
