Here!! I got it working just great.

address@hidden test]$ cat Makefile
#!/usr/bin/make -f

PRELFSH:=/bin/sh -c "$$(printf '
POSTLFSH=' | sed -e 's/\\$$//')"

.PHONY: all

all: helloworld
        @./helloworld

helloworld:
        @$(PRELFSH)gcc -E -o - - <<'\''EOF'\'' | gcc -x c -o helloworld - \
#include <stdio.h>\
int main( int argc, const char* argv[] ) {\
    printf("Hello World!!!\\n");\
    return(0);\
};\
EOF$(POSTLFSH)

address@hidden test]$ make -B
Hello World!!!
address@hidden test]$
