Re: [ft] Freetype2 compilation error

[suzuki toshiya]

Dear Amit,

Thanks again! According to the line

> "./cpp-bitshift-test2.c", line 11.32: 1506-207 (W) Integer constant 
> 0x100000000L out of range.

the integer constant greater than 32-bit is inappropriate
for xlc's cpp. I think FreeType2 header for xlc should not
be shared between 32-bit and 64-bit systems. I will investigate
any predefined macros to detect xlc (or the case that the
max sizes of the integer constants are different between
cpp & C compiler), but the immediate fix for the next release
of FreeType2 would disable the bi-arch header file.

Regards,
mpsuzuki
