I've been fighting with getting here documents to work as part of a make

Here!! I got it working just great.

The issue I have with this is simple....

Escape data for make.  Obviously this is acceptable ;)
Then escape the data for shell/printf/ect. Here is the big conundrum, it's way to difficult to think about how this get's unwrapped and to debug the results.

Is there a simpler way that I'm overlooking? Obviously I'm overlooking having a make file and then several data files with out using here documents.... That's not the solution I'm looking for, I'd have to use what I have instead.

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

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

.PHONY: all

all: 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");\

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