* Add support for more drivers to shgen !!!!* shgen relies on having a gnu-compatible getopt, which should be  available on all hosts using gcc/egcs/binutils.   Using other getopt-variants may produce faulty results or shgen may also  refuse to compile. Probably the easiest solution to this problem would be   to integrate libiberty into rtems.* shgen uses floating point mathematics. Therefore Makefile.in contains a   reference to libm. In case the host doesn't have its floating point  support in libm, shgen will fail to compile. If we should ever meet such   a host, checks for floating point libraries have to be added to rtems'  autoconf support.
