Summary: Problems with -Wundef and -Werror

Initial Comment:
Hi.

I have a few preprocessor-related problems, and here
at BTS there seem to be no category for the
preprocessor, which is also a bug:)

1. string.h is not -Wundef-resistant. I think the fix
could be as simple as the patch attached.

2. It seems -Werror doesn't work. Compiling the code
like:
---
#if UNDEF
#error TEST
#endif

char main()
{
  return 0;
}

---
this way:

$ sdcc -Wp,-Wundef -Wp,-Werror prepr.c 
prepr.c:1:5: "UNDEF" is not defined

still produces an asm and .ihx output, not returning
an error status to "make". I think it should.

Also it would be nice if sdcc is to accept the
-Wundef and -Werror directly, the way gcc does,
but that's really an RFE.

The bug tracker now has a "C Preprocessor" catagory.

device/include/string.h 1.10 is now -Wundef compatible.

src/SDCCmain.c 1.195 will now abort with a non-zero exit
code (and not assemble or link) if the preprocessor returns
a non-zero exit code.
