Indeed, GAP -5 preserves the angle properly, while GAP 5 does not.

Is this the intended behavior, or just a workaround given some bug?  I can't
find anything in the documentation that suggest this.  I would have thought
that a negative gap would have flipped everything around in the opposite
direction.

From
http://mapserver.gis.umn.edu/docs/reference/symbology/referencemanual-all-pages

--- begin ---
GAP [int]

    Given in pixels. This defines a distance between symbols for TrueType
lines. As of MapServer 5.0 this also applies to PixMap symbols.

    When drawing the symbol along a line segment, a negative GAP will will
add 180 degress to the angle. The TrueType and PixMap symbols are always
oriented along the line. A GAP of 0 (the default value) will cause MapServer
to use the symbol as a brush to draw the line.
