[slang-users] SLprep_set_eval_hook() usage

["Gisle Vanem" <gvanem@xxxxxxxx>]

Hi list.

I'm trying to extend my small S-Lang powered preprocessed makefile
(modelled after mkmake.c in ./src) to return the Windows SDK-version
my input file is targeting.

My idea was to map values from GetVersionEx() into '-D_WIN32_WINNT=0x??'
values (assuming the SDK match the OS-ver). How do I do this best? 

I tried using the 'SLprep_set_eval_hook()' function and in my makefile:
 @if $WinDir
 @if (CFLAGS = -D_WIN32_WINNT=0x??)
 @endif

And see that my hook is called with 
 '(CFLAGS = -D_WIN32_WINNT=0x??)\n'

Is the only way for hook to be called if the line starts with '@if ('?
If so, do I simply copy the '-DCFLAGS = _WIN32_WINNT=0x0x501'
back into the 'expr' buffer? The docs on this very dim IMHO.
