Hi all,

Two questions:

1.  Are fixincludes hacks only active during build-time (e.g. they do 
not replace the actual file) or are they permanent?  If they are only 
temporary/local to gcc, but they need to be permanent, is there a way to 
specify this?

2.  On cross compilers, fixincludes does not appear (to my uneducated 
eye) to be applied to my headers (then again, I may have written the 
hacks wrong) located in sys-include.  Does fixincludes not affect 
headers in sys-include or am I not looking hard enough?

If somebody can explain in a bit more detail how fixincludes works (I 
read the README but it only defines the formatting), please do.

The hacks I'm trying to apply are at the end of this email, if it helps.

Thanks,

Robert Mason
