I'm trying that idea (using CC=g++ on Linux) on M4 before releasing m4 1.4.8.  
Is it worth fixing the vasnprintf module?

g++  -I.     -g -O2 -MT printf-parse.o -MD -MP -MF .deps/printf-parse.Tpo -c -o 
printf-parse.o printf-parse.c
printf-parse.c: In function `int printf_parse(const char*, char_directives*, 
arguments*)':
