I guess leaving it 1 for mycrypt.c is fine. Does AIX have some "AIX"
macro defined? So I could change fdpass.c to have:

#ifndef AIX
#  define _XOPEN_SOURCE_EXTENDED /* for Tru64, breaks AIX */
#endif

Hmm.. This is quite likely because struct mail_index_data_record_header
isn't padded to take 8 bytes with 32bit off_t. Has all systems until now
really had 64bit off_t? This should fix it:

But I'm not sure if I want to commit this change. Maybe some systems
have added the padding elsewhere? Changing the location could break
things. After next release I'll break the index files anyway, I think
I'll leave this fix until then.
