Changeset 1895 for trunk/m4/yat_gsl.m4

Message:

fixes #386. Add test that gsl header files are available. Add 'GSL_CONFIG --cflags' to CPPFLAGS (unless it's a default path) to make the test work also when header files are installed in non-standard location. The flag is stored and used downstream.
