Warning: argument -pedantic, forcing local preprocessing - even with -std flag specified

[mliszcz]

I noticed this warning with gcc 12.2.0:

ICECC[13224] 2024-03-18 14:34:38: argument -pedantic, forcing local preprocessing (try using -std=cXX instead of -std=gnuXX)

Indeed we have -Wpedantic BUT we also have -std=c++17.

The check is implemented here:

icecream/client/arg.cpp

Lines 891 to 897 in 9d397ef

	// -pedantic doesn't work with remote preprocessing, if extensions to a named standard
	// are allowed. GCC allows GNU extensions by default, so let's check if a standard
	// other than eg gnu11 or gnu++14 was specified.
	if( seen_pedantic && !compiler_is_clang(job) && (!standard || str_startswith("gnu", standard)) ) {
	log_warning() << "argument -pedantic, forcing local preprocessing (try using -std=cXX instead of -std=gnuXX)" << endl;
	job.setBlockRewriteIncludes(true);
	}

The standard variable is declared on top but never assigned:

icecream/client/arg.cpp

Line 319 in 9d397ef

const char *standard = nullptr;

Is remote preprocessing supposed to work as described in the warning message/comment? If yes and it was overlooked, I can send a PR.
