The configure script runs the compiler. If the compiler fails once then 
passes, with the exact same command-line, it's the compiler's fault. On the 
other hand, if the configure script is running something different on the 
second run, then it's the configure script's fault.

Anyway, let's stop speculating. Until we can reliably reproduce this problem 
to understand what's going on, we're shooting in the dark.
