[ft-devel] Build errors with MSVC

[John Emmas]

Hi guys, I updated freetype from git master (this morning) and I'm 
getting these errors when compiling cff.c (technically, when compiling 
cffobjs.c):-

    src/cff/cffobjs.c(1095) : warning C4003: not enough actual 
parameters for macro 'SET_DARKENING_PARAMETERS_0'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : '<'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'
    src/cff/cffobjs.c(1095) : error C2059: syntax error : ';'

As you can see, the errors are all at line 1095 of 'src/cff/cffobjs.c'.  
Lines 1094 and 1095 look like this:-

    SET_DARKENING_PARAMETERS( driver,
                              CFF_CONFIG_OPTION_DARKENING_PARAMETERS );

Prior to this morning's update, that same section previously looked like 
this AFAICT:-

    driver->darken_params[0] =  500;
    driver->darken_params[1] =  400;
    driver->darken_params[2] = 1000;
    driver->darken_params[3] =  275;
    driver->darken_params[4] = 1667;
    driver->darken_params[5] =  275;
    driver->darken_params[6] = 2333;
    driver->darken_params[7] =    0;

So my guess is that some kind of problem's crept in when converting all 
that lot to a macro.  My first thought was that maybe 'ftoption.h' 
wasn't getting #included, so I deliberately #included it but that didn't 
make any difference.

I then changed lines 1094 and 1095 to look like this (note that it now 
uses 'SET_DARKENING_PARAMETERS_0'):-

    SET_DARKENING_PARAMETERS_0 ( driver,
                              500, 400, 1000, 275, 1667, 275, 2333, 0 );

The above seems to compile successfully.  So I then tried this:-

    SET_DARKENING_PARAMETERS_0 ( driver,
                              CFF_CONFIG_OPTION_DARKENING_PARAMETERS );

but that gets me back to the same set of errors that I had in the first 
place.  So I'm guessing that MSVC is objecting to something about 
'CFF_CONFIG_OPTION_DARKENING_PARAMETERS'.  Are there any other tests I 
could do that might help track this down?
