He is. A quick search on google for "C beautify" yields bcpp (and other
programs). I was aware of one from years ago called cb, but couldn't find
it (not on redhat distro, 5 minutes of search didn't find it). CBPP appears
to be something similar, but supporting C++ as well as C. I suspect that he
can try "gcc -E file.c | cb > file.fmt" or some such (assuming cb and bcpp
support stdin/stdout data transports).

Maybe I misunderstood the question. I thought the problem was to get
from
#define F { \
bla; \
}
F
to
{
bla;
}
whereas gcc -E produces
{ bla; }
