Re: Some issues wrt compilation on Windows using VS.NET

[John]

As far as we know, Flex builds fine on Windows under Cygwin. What
would compiling under .NET give us?

I'll address the big points briefly now, so you don't waste your time
on them:

Nor is it possible on  BSD, since the standard streams are not
lvalues.  I intend to fix the problem by duplicating the pipes as
fileno(stdin) and fileno(stdout).

popen() won't help. Flex doesn't exec every time it forks. As I
understand, pipe/fork/exec/wait are available everywhere except
.NET...
