to reduce the current compilation output, type
(just filters the compilation lines with sed, stderr still visible). At some
point one could introduce a config.h file, which is used to pass all the
compile switches determined by configure to the preprocessor, so the awfully
long compile lines would get shorter. But this requires adding a include
directive to all source files, so I did not want to do it now.
To build the test files (e.g. for crypto and mon stuff)
They will never be installed by make install (the check target is just for
compiling and running a package's tests. At some point one could add some
active tests to this target).
this will ensure, that a generated tarball can indeed compile.
