# Translate absolute paths from POSIX to Windows. Use bash array to store
# arguments in case they contain spaces.
#
# This needs to be done for both certain option values and arguments.
# Arguments are tricky in that unless we recognize every option, and option
# may look a lot like an absolute POSIX path (e.g., /nologo). The heuristics
# that we are going to use here is that if the argument starts with / and
# contains at least one more /, then we consider it an argument. Otherwise --
# an options. We will also explicitly recognize certain options which may not
# fit this scheme well.
#
# Note that the order of the cases is important. Specifically, we want, e.g.,
# /D before /D*.
#
# Note that rc.exe /? is missing some options that are documented in MSDN.
