So? When there's only one choice, 'standard' means about as much as 
'default', 'prefered' or 'developer's choice'. That is to say, fuck all. If
any
of the main PC compilers were available for Linux, would people use gcc?

Just because the spec sheets don't say that something is possible doesn't
necesserily make it impossible. (E)COFF is a portable object format, and 
from a quick look at some VC5 object files, they look to be COFF objects.
This happens to be the same format as gcc so, in theory, the compilers
and linkers can be interchanged - and code can be compiled under 
windows and linked under Linux.

Do you have any idea how many professional programmers you're calling
idiots?

The Pentium will be dead in a year. FFS, the entry level is a P166-P200,
and
they only go up to a 233! By the time DJGPP supports the Pentium, most
professionals will be targetting Pentium-2s, with Pentium compatability as
a
side-issue.

VC4 isn't current, and even so, it beats DJGPP. Just saying DJGPP
is faster doesn't make the code it produces any better.

Unless you actually want to do some work with your compiler...
