I doubt that the (compiler) warning is responsible for the (linker) failure.

When I am faced with problems like this (usually during extension building;
I have never encountered a problem during a Python built), I try
to find out what (OS level) commands are executed by the build machinery
and then issue them manually on the command line: the build machinery
often hides error details revealed by executing the commands
directly on the command line.


What I can imagine is that your (OS level installed) C libraries (i.e. "libc"
and friends) no longer contain a "tempnam", letting the linker fail.
Thus, maybe, the compiler still warns about "tempnam" but the linker
already considers it as an error.
