# Default for COMPILER_WARNINGS_FATAL on Windows (C++ compiler warnings)
#    Level: Default is 3, 0 means none, 4 is the most but may be unreliable
#    Some makefiles may have set this to 0 to turn off warnings completely,
#    which also effectively creates a COMPILER_WARNINGS_FATAL=false situation.
#    Program.gmk may turn this down to 2 (building .exe's).
#    Windows 64bit platforms are less likely to be warning free.
#    Historically, Windows 32bit builds should be mostly warning free.

# WARNING: This is extremely touch stuff, between CYGWIN vs. MKS and all
#          variations of MKS and CYGWIN releases, and 32bit vs 64bit,
#          this file can give you nightmares.
#
# Notes:
#   Keep all paths in the windows "mixed" style except CYGWIN UNXIXCOMMAND_PATH.
#   Use of PrefixPath is critical, some variables must end with / (see NOTE).
#   Use of quotes is critical due to possible spaces in paths coming from
#     the environment variables, be careful.
#   First convert \ to / with subst, keep it quoted due to blanks, then
#     use cygpath -s or dosname -s to get the short non-blank name.
#   If the MKS is old and doesn't have a dosname -s, you will be forced
#     to set ALT variables with the short non-space directory names.
#     If dosname doesn't appear to work, we won't use it.
#     The dosname utility also wants to accept stdin if it is not supplied
#     any path on the command line, this is really dangerous when using
#     make variables that can easily become empty, so I use:
#        echo $1 | dosname -s     instead of    dosname -s $1
#     to prevent dosname from hanging up the make process when $1 is empty.
#     The cygpath utility does not have this problem.
#   The ALT values should never really have spaces or use \.
#   Suspect these environment variables to have spaces and/or \ characters:
#     SYSTEMROOT, SystemRoot, WINDIR, windir, PROGRAMFILES, ProgramFiles,
#     MSTOOLS, Mstools, MSSDK, MSSdk, VC71COMNTOOLS, 
#     MSVCDIR, MSVCDir.
#     So use $(subst \,/,) on them first adding quotes and placing them in
#         their own variable assigned with :=, then use FullPath.
#
