Current Symbian^3 public API header files (from PDK 3.0.h)
This is the epoc32/include tree with the "platform" subtrees removed, and
all but a selected few mbg and rsg files removed.

    68  * The purpose of this header file is for supporting 64-bit integer
    69  * manipulation on 32-bit (and lower) machines.  Currently the only
    70  * such environment is VMS, Utrix and those with smaller default integer
    71  * sizes than 32 bits.  For all such environment, we fall back to using
    72  * BIGNUM.  We may need to fine tune the conditions for systems that
    73  * are incorrectly configured.
    74  *
    75  * The only clients of this code are (1) pqueue for priority, and
    76  * (2) DTLS, for sequence number manipulation.
