develop branch - support for printf with no parameters

[GiovanniCmpaner]

I'm trying to use printf with empty parameters, like:

printf("Just a debug string")

Currently, I get a compiler error with the original code.

The solution is to change these lines:

PrintEx/src/lib/PrintExtension.h

Lines 202 to 203 in 7e13cfc

	#define sprintf(buff, str, ...) GString(buff).printf(str, __VA_ARGS__)
	#define xprintf(out, str, ...) PrintEx(out).PRINTF_ALIAS(str, __VA_ARGS__)

PrintEx/src/lib/PrintExtension.h

Line 208 in 7e13cfc

#define printf(format, ...) PRINTF_ALIAS(format, __VA_ARGS__)

To:

#define sprintf(buff, str, ...) GString(buff).printf(str, ##__VA_ARGS__)
#define xprintf(out, str, ...) PrintEx(out).PRINTF_ALIAS(str, ##__VA_ARGS__)

#define printf(format, ...) PRINTF_ALIAS(format, ##__VA_ARGS__)

Note the leading ## in __VA_ARGS__

What is the status of this issue. Seems like something that should get fixed for sure.
