+# 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.
