GPGME Large File Support on HPUX (seek)

I'm having some problems with GPGME (1.1.4) and GPG (1.4.7) and the
large file support compile time options.  I have compiled this on HPUX
11.00 and when I run the following C sample I get odd file offset
results.  I have tried building GPGME with both CFLAGS set to

---- sample ----
#include <gpgme.h>

main (int argc, char *argv[])

        gpgme_data_t  in;
        off_t   len;
        gpgme_error_t err;

        err = gpgme_data_new_from_mem(&in, "Hallo Leute\n", 12, 0);
        printf("new_mem:%d %s->%d\n", __LINE__, gpgme_strerror(err),

        len = gpgme_data_seek(in, 0, SEEK_SET);
        printf("Offset SEEK_SET = %d\n", len);

        len = gpgme_data_seek(in, 0, SEEK_END);
        printf("Offset SEEK_END = %d\n", len);

Compiling as: 

1) gcc b.c `gpgme-config --libs --cflags` -D_FILE_OFFSET_BITS=64
new_mem:12 Success->0
Offset SEEK_SET = 27907
Offset SEEK_END = 1073762736

2) gcc b.c `gpgme-config --libs --cflags`
new_mem:12 Success->0
Offset SEEK_SET = -1
Offset SEEK_END = -1

I have read through similar posts and they all point to reading section
2.3 which refers to using the _FILE_OFFSET_BITS=64 and
LARGEFILE_SUPPORT=1 and building gpgme with large file support.  When I
build with both preprocessor symbols I get:

3) gcc b.c `gpgme-config --libs --cflags` -D_FILE_OFFSET_BITS=64
new_mem:12 Success->0
Offset SEEK_SET = 29206
Offset SEEK_END = 1073762752

Any suggestions or pointers would be greatly appreciated.
