org.eclipse.cdt.core patch to add support for binary constants

GCC has supported binary constants (prefixed with 0b or 0B) since 4.3.0,
see http://gcc.gnu.org/onlinedocs/gcc/Binary-constants.html

Some GCC derivatives (like avr-gcc) and some other C compilers have supported binary constants even longer.

However CDT flags them as "Invalid decimal format" in the source editor. As eclipse/CDT is already popular for embedded processor work, binary constants should be supported by CDT.

I have attached a patch to org.eclipse.cdt.core to add this support to the parser scanner.

Also attached is a patch to org.eclipse.cdt.core.tests containing a small test case for binary constants.

I have run the full CDT test suite against the patch and there seem to be no side effects.

The patch is fairly straightforward and on behalf of many bit-fiddling programmers I would appreciate it if this patch could be included in one of the next CDT releases.

brgds,

Thomas
