9# Convert the specified POSIX path to a Windows path under MinGW and Cygwin
10# The optional second parameter specifies the level of backslash escaping
11# to apply for each Windows backslash position in order to support varying
12# levels of variable substitutions in scripts.
13#
14# Note that Cygwin includes the 'cygpath' utility, which already provides
15# path translation capability.
