How can I convert a Cygwin style path ( /cygdrive/c/foo/bar ) to Windows style ( C:/foo/bar ) (yes, with / going forward) in a GNU makefile? I have the situation of using Cygwin's make with a GCC that does not understand Cygwin style paths, so paths relative to the makefiles location that are produced by make are not accepted by the compiler.

Use the shell function to execute the cygpath utility with the -w flag.

Example:

BAR := /cygdrive/c/foo/bar
WIN_BAR := $(shell cygpath -w ${BAR})

cygpath accepts a lot of additional options. See the man page for details.
