Those threads are mostly about getting DMD to predefine Posix or Unix.  That's
not what this bug is about.  This is about the capitalization of "Linux" being
inconsistent, and that's it.

The second thread does include this rationale for "version(linux)" from Walter:

"""
The reason DMD uses "linux" is because gcc under Linux predefines "linux". 
"""

I have no idea why DMD should define its Linux version identifier based on
GCC's behavior, rather than doing something consistent and which makes sense
for D.  But even if for some bizarre reason people feel that D's versions
should follow the conventions of #defines established by some particular
implementations of C, there's still an inconsistency, because the preprocessor
symbol predefined on Windows systems is not "Windows" or "Win32", but rather
"WINDOWS" or "WIN32" or "_WIN32".
