The reason I needed to compile GCC in order to implement 
the math library, was that I wanted to make the key parts of it
as flexible inline assembler macros, i.e. a .md file.

Well, I have the complete GCC source three from gcc-2.7.2.tar.gz and
from gcc-2.7.2.1.tar.gz, your patchfile, and NetBSD src/gnu which
is sup'ed, and your recommended compiler flags. 

Neither of them compiles. I have tried several combinations
of these, and permutations, and gotten a little bit more to compile,
but not enough.

What you have got seems to be different from what is available to others.
Perhaps I should accept your generous offer of a complete copy?

Probably. But the time and work needed to do so is too excessive.
And I would not make patches, but kludges, since my knowledge of
the rest of GCC and NetBSD is nowhere near yours. My knowledge
about numerics might be fuller than yours. So my time is better
spent doing that.

Well, I tried that. I fetched GCC for the 4th time, as gnu.tar.gz tonight,
from ftp.NetBSD.ORG.

It compiled further, but not all. Here is the divergent point. Isn't this the
same as Ale Terlevich got? He obviously has a faster internet connection
than I.
