Subject: * aesopt.h: On PalmOS, include FloatMgr.h to get endianness flag.
X-Git-Tag: ms-bug-test-20060525~286
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f0b00252909f0db54226a30f57a2d44b4d79a1e7;p=krb5.git

* aesopt.h: On PalmOS, include FloatMgr.h to get endianness flag.
(ENC_UNROLL, DEC_UNROLL, ENC_ROUND, LAST_ENC_ROUND, DEC_ROUND, LAST_DEC_ROUND,
KEY_SCHED): If CONFIG_SMALL is defined, set to NONE or NO_TABLES as
appropriate.

(Latter change drops about 40K -- over 85% -- from AES code/table size in
shared libraries on x86/glibc/gcc.)
