Re: [ft] freetype2 and Win64

[mpsuzuki]

Thank you for info.

It seems that now precompiled binaries of mingw-w64
for 32-bit Linux platform are not provided (the last
binaries are released on 2009-06-04). I will compile
the toolchain from source package, please wait one week
or so.

Regards,
mpsuzuki
