Yeah, easy enough to hack that together relatively quickly. I added a new
command line option to the Wave tool --macrocounts/-c allowing to specify a
file name (or '-' for stdout) where the tool will print the names and
invocation counts of all expanded macros. The best way to profile macro
expansion counts seems to be 'wave -c- -o- ...include paths... filename',
where -c- prints the counts to cout and -o- suppresses any output from the
