windres CANNOT process the stringify macro!

I found the windres.exe cannot process the stringify macro.

windres 2.21

test code:
test.rc file
=======================

#define MAJOR_VERSION 1
#define MINOR_VERSION 2
#define PATCH_VERSION 3

#define STRINGIFY_HELPER(n) #n

#define VERSION \ STRINGIFY_HELPER(MAJOR_VERSION) "." \ STRINGIFY_HELPER(MINOR_VERSION) "." \ STRINGIFY_HELPER(PATCH_VERSION)

#define VERSION_CSV MAJOR_VERSION ##, \ ##MINOR_VERSION ##, \ ##PATCH_VERSION
1 VERSIONINFO
FILEVERSION VERSION_CSV,0
PRODUCTVERSION VERSION_CVS,0
FILEFLAGSMASK 0x3fL
FILEFLAGS 0x02L
FILEOS 0x40004L
FILETYPE 0x1L
FILESUBTYPE 0x0L
BEGIN
BLOCK "StringFileInfo"
BEGIN
BLOCK "040904b0"
BEGIN
END
END
BLOCK "VarFileInfo"
BEGIN
VALUE "Translation", 0x409, 1200
END
END
===============================

Compile the test.rc file and get the error.

./res.rc:16:1: error: pasting "MAJOR_VERSION" and "," does not give a valid preprocessing token
./res.rc:16:1: error: pasting "," and "MINOR_VERSION" does not give a valid preprocessing token
./res.rc:16:1: error: pasting "MINOR_VERSION" and "," does not give a valid preprocessing token
./res.rc:16:1: error: pasting "," and "PATCH_VERSION" does not give a valid preprocessing token
i486-mingw32-windres: ./res.rc:17: syntax error
i486-mingw32-windres: preprocessing failed.

I caught this bug when I try to compile Apache with mingw32
