This is a hack to check the consistency of the .def files compared to
|
|
the respective libraries.
|
|
|
|
Invoke in the top level of the gimp source tree after compiling GIMP.
|
|
If srcdir != builddir, run it in the build directory and pass the name
|
|
of the source directory on the command-line.
|
|
|
|
Needs the tool "nm" to work
