[ft-devel] freetype-2.3.7 -- ftconfig.h for biarch systems

[Peter Breitenlohner]

Hi,

For various reasons I have to install on our linux-x86_84 systems
the 64 bit version of libfreetype (in /usr/lib64/) as well as the
32 bit (linux-i686) version (in /usr/lib/).

So far, no problem.

However, the headers installed in /usr/include/freetype2/freetype/ differ at
one point:

config/ftconfig.h contains (SIZEOF_LONG being replaced by 8 or 4)
        #define FT_SIZEOF_LONG 8
for the 64 bit version, and
        #define FT_SIZEOF_LONG 4
for the 32 bit version.

Of course, the same kind of problem occurs for other biarch systems such as
ppc/ppc64, sparc32/sparc64, etc.

In order to have headers usable for both 32 and 64 bit mode, that ought to
be replaced by something like

(1) for systems with <bits/wordsize.h> (should include all biarch systems)

        #include <bits/wordsize.h>
        #if  __WORDSIZE == 64
        #define FT_SIZEOF_LONG 8
        #else
        #define FT_SIZEOF_LONG 4
        #endif

(2) for systems without <bits/wordsize.h>

        #define FT_SIZEOF_LONG SIZEOF_LONG

Getting this result might require some autoconf magic, but should not be
overly difficult.
