While not all flags affect code generation, it doesn't seem unreasonable
to make sure that at least all -m*, -f*, and -g* flags are the same.  It
doesn't sound very safe, or maintainable, to keep track of which flags
do affect PCH and which don't.  Getting all the GTYs right has turned
out to be hard enough ;-)

Seriously though, how likely is it that people will use different flags
for their PCH than for their normal compilation?  Doesn't Joe User
typicaly just use "-O[123] -g"?

I'd rather be safe and make sure all flags match than chasing flag bugs
for PCH...
