X-Git-Tag: fc-2_3_94~56
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=971cf18018a4f41bca196dd81989e67672e52112;p=fontconfig.git

Add documentation for FcConfigNormalizeFontDir.
Write directory information to global caches to fix make check (reported by
    Ronny V. Vindenes). This changes the global cache format again.
