Good.  What about H5_STDC_HEADERS?

Good.

The BUILTIN_TYPES_ONLY change was good for experimentation but is
not expected to fix the build.

The off64_t is supposed to be defined in sys/types.h when the large file
API is enabled.  I think that H5pubconf.h is defining _LARGE_FILES which
may hide the "64" names and replace the raw names (off_t) with 64-bit
versions.  The _LARGE_FILES macro is not defined during the try-compile,
leading to the inconsistency.  Please try this:

  echo "#include <sys/types.h>" > types.c
  /local/bin/gcc -E types.c -dD > types_default.c
  /local/bin/gcc -E types.c -dD -D_LARGE_FILES > types_LARGE_FILES.c

and send me the output files (off-list).

Thanks,
