Yes, to be clearer what Levente means is that you should use:

  %{_mingw32_configure}

in RPM specfiles, and if just building from the command line use:

  mingw32-configure

Both are merely wrappers around this basic command:

  ./configure --host=i686-pc-mingw32

except that they set a lot more paths and a environment variables,
which are needed in rarer / corner cases.

The full expansion is below for anyone who is interested, although
only PKG_CONFIG_PATH is needed in 95% of cases.

Rich.
