[Distutils] setting string macros

[Robin Becker]

I'm having a problem win32 vs freeBSD/unices

under win32 the executed command string appears like this

-DLIBART_VERSION=\"2.3.10\"

so the setup.py code looks like

define_macros=[('LIBART_VERSION','\\"2.3.10\\"')]

but this causes problems with unices (unterminated string constant
errors) and I have to use

define_macros=[('LIBART_VERSION','"2.3.10"')]

I guess this relates to problems in system under win32, but is there a
'correct' way to get string macros defined.
