Actually, this message is only a warning, and should not prevent a
successful build of pcb.

What "gcc --version" gives you? Is it 4.3.4?
Curiously, when I tried it myself, the build succeeded with gcc 3.4.4,
but failed with undefined references when switching to gcc 4.3.4. They
seem to be related to some inline functions in toporouter.c. I will try
to narrow it down.
Meanwhile, you could try switching to gcc 3.4.4:
1) Install gcc-core from Cygwin Setup
2) chmod +x /usr/bin/set-gcc-default*
3) set-gcc-default-3.sh
4) gcc --version (should be 3.4.4)
5) Rebuild pcb from scratch.
Or, alternatively, keep gcc 4.3.4, but remove all "inline" keywords from
toporouter.c.
