>Description:
Just thought it would be nice to able to have a makefile containing eg.

PROG=   pms
SRCS=   scan.ll
LDADD+= -lstdc++ -ll
.include <bsd.prog.mk>

to generate a c++ scanner.
1) Who knows whethere ll is a good choice of suffix?
2) I am not sure how to test it thoroughly.
3) Who knows whether it is worth having?
All I can say, is it seems to work, though due to a ?deficiency? in
?src/usr.bin/lex/flex.skl?, I do need to include
static void *yy_flex_realloc( void *ptr, yy_size_t size );
static void yy_flex_free( void *ptr );
static void *yy_flex_alloc( yy_size_t size );
in the .ll file, but that's a different problem.
