Insert EndianS16_BtoN and EndianS32_BtoN as workaround for
Intel Mac. The original patch was written by David Sachitano
and Lawrence Coopet, modified by Sean McBride for MPW
compatibility. Only required data are converted, unused data
are left in big endian.
* src/base/ftmac.c:
Undefine existing OS_INLINE before definition.
Include <Endian.h> for byteorder macros for non Mac OS X
platforms.
(count_faces_sfnt): Insert EndianS16_BtoN to parse the header
of FontAssociation table in FOND resource.
(count_faces_scalable): Insert EndianS16_BtoN to parse the
header and fontSize at each entry of FontAssociation table
in FOND resource.
(parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to
parse ffStylOff of FamilyRecord header of FOND resource,
the header, fontSize, fontID at each entry of FontAssociation
table, and StyleMapping table.
(count_faces): HUnlock is suspended after all FOND utilization.
