Discussing about "Building a development environment for Windows"

'which EXECUTEABLE' is unix command looking up where if anywhere in the path the exectuable is first.

for example:
~/src/wings (dgud/wx-backend):> which ls
/bin/ls.exe
~/src/wings (dgud/wx-backend):>

But as Micheus just said you must have it in your PATH variable to find it,
which btw I don't :-)
