I am quite sure AJ will object to any such things - as far as the various
compilers (and windows applications in general) are concerned, they should just
believe they are running under windows. If a compiler (or a windows application)
behaves differently under Microsoft Windows vs under wine, it is a bug for wine.
AFAIK, the only "recommended/supported" way for an application to tell that it
is running under wine vs under windows is by querying the presence of one of
wine-specific registry entries. It is quite "evil" for a compiler to query the
registry. Microsoft compilers probably try to probe the host about which
versions of windows it is running in to work around "silently" various bugs in
different/older versions of OSes which are fixed later, but I doubt any mingw
people or GNU people for that matter, want to go down that path.
In other words, don't even think about it.
