Using bison3 on mingw

[Dimitri Merejkowsky]

Hi,

I'm trying to use bison3 on windows, and could not find any binary
distribution, so I'm building it
from source, using a mingw environment.

Compilation works fine, but then when I try to run the tests I get:

examples/calc++/calc++-parser.yy: fatal error: invalid @ in skeleton: @

I found this

https://bugs.launchpad.net/ubuntu/+source/bison/+bug/481704

and that:

but with no luck.

Some version numbers:
m4 1.4.17
flex 3.5.35
bison 3.0.2
