cpplib and endianness problems

[Neil Booth]

I noticed a few weeks ago that Sparc was failing on gcc.dg/cpp/if-2.c

Unfortunately, there was more than one test on the line it was failing
on, so I separated the tests to see which one it was.

>From recent posts to gcc-testresults, like Kaveh's, we see the
following fails on Sparc:

#if L'\xfeed' != 0xfeed
#error 0xfeed	/* { dg-bogus "error" "wide charconst recognition 2" } */
#endif

I have no idea if this test is valid; i.e. how should we be
interpreting L'\xfeed'?  Should it be equal to 0xfeed?
