Wholly inadequate???
Just for the record, did you actually read the whole message? Sure,
Mark did not mention the exact phrase "cross compiler" anywhere
in that message, but surely you can't blame him for anticipating
that you needed to know that? Some four years ago?
I think he has it just about right.
Here's an interesting quote from further down in that message
that you apparently didn't read:
"I don't think that inserting the Cygwin run-time code into
the executable is a feasible route (from a technical or
licensing standpoint) but avoiding the Cygwin run-time code
via the -mno-cygwin switch surely is."
I.e. Mark states pretty clearly that -mno-cygwin means that no
cygwin code is involved in the resulting binaries. He also
pretty clearly eliminates any static linking with the first
half of that sentence (if run-time somehow implies dll in your
world).
Cheers,
Peter (who does not know Mark)
