DCMTK

When dcmdump is run on a big-endian CPU in order to print the contents of the attached file, which contains a meta-header but no dataset, then the following output is created:

# Dicom-File-Format

# Dicom-Meta-Information-Header
# Used TransferSyntax: Little Endian Explicit
(0002,0000) UL 202                                      #   4, 1 FileMetaInformationGroupLength

# Dicom-Data-Set
# Used TransferSyntax: Big Endian Explicit

Note that the metaheader specifies "LittleEndianExplicit" as the transfer syntax of the main dataset, while the dataset itself reports "Big Endian Explicit".
This is a minor issue since it only affects files with empty datasets, which should never occur in practice, but is still undesirable.
