This is with Linux defaults:

~/cvs/dovecot-1.2% grep PREAD config.h
#define HAVE_PREAD 1
/* #undef PREAD_BROKEN */
#define PREAD_WRAPPERS /**/

~/cvs/dovecot-1.2/src/master% nm dovecot|grep pread
080685a0 T my_pread
         U pread64@@GLIBC_2.1

This is with pread() disabled:

~/cvs/dovecot-1.2/% grep PREAD config.h
//#define HAVE_PREAD 1
#define PREAD_BROKEN
//#define PREAD_WRAPPERS /**/

~/cvs/dovecot-1.2/src/master% nm dovecot|grep pread
0806ade0 T my_pread

Note how there's no pread64@@GLIBC_2.1 symbol at all. What about in your
binaries?
