FMSLogo Code

Fix an off-by-one bug that prevent cnv_node_to_intnode() from returning an int node when the number was FIXNUM_MAX.

Fix a memory corruption bug in ranged_integer_arg that was introduced during some recent refactoring.

Add missing #include to fix build breaks when not compiling with a precompiled header.

Add additional test variations for parsing numbers.

Fix bug #338; SETACTIVEAREA now throw errors when given non-integer values.

This required a little refactoring of the argument and conversion logic to provide an "integer only" argument checker.

This revision also includes a regression test that SETACTIVEAREA persists the new settings to the configuration.

Add function comments to numberp()

Add a function to uninitialize the DLL subsystem. This cleans up memory which a Logo programmer may have forgotten. It also fixes an assert failure in the case when DLLFREE is not called.

Enable the procedures in term.cpp under WX_PURE.
This unblocks running the screen.lgo tests on GNU/Linux.

Use the same flags for CCommanderDialog, regardless of platform.
I don't remember why different platforms had different flags, but I
expect that I had misread some documentation that wxSYSTEM_MENU didn't
exist on UNIX.

Don't register an event handler for EVT_STC_CLIPBOARD_PASTE on
wxWidgets versions less than 3.1.0, where it is not defined. This
unblocks further development for Fedora Core, whose most recent
wxWidgets library is 3.0.2.
