Not that I know any easy way.

Hmm.. I'd suggest this trick:

project your_project : requirements <toolset>gcc:<cflags>"-x c++" ;

This will produce command lines like:

gcc.compile.c bin/gcc/debug/a.o

"g++" -x c -Wall -O0 -fno-inline -g -x c++ .....

And the second "-x" option will override the first one.

HTH,
