 Hi,

 with g.setproj it is possible to set the region so that the resulting
 PROJ_INFO file is missing the zone: field. Perhaps
 this is because 'g.region -p' says the zone is -55 while g.proj
 had 55(S)?

 {{{
 G640rc2> g.setproj
 ...
 Would you still like to change some of the parameters?(y/n) [n] y
 WARNING: Zone in default geographic region definition: -55
          is different from zone in PROJ_INFO file: 55
 ...
 Please specify projection name
 >utm
 }}}
 [ do we want a space after the '>' prompt? ]
 {{{
 Do you wish to specify a geodetic datum for this location?(y/n) [y] y

 Please specify datum name
 >custom
 }}}
 [I did want the datum to be Australia GD 1994, but that's not a choice]
 {{{
 Please specify ellipsoid name
 >grs80

 Please specify datum transformation parameters
 >towgs84=0,0,0

 Parameters to be used are:
 "towgs84=0,0,0"
 Is this correct?(y/n) [y] y
 South Hemisphere(y/n) [n] y
 The UTM zone is now set to 55
 Do you want to change the UTM zone?(y/n) [n] n
 UTM zone information has not been updated

 Projection information has been recorded for this location
 }}}

 then

 {{{
  g.proj -p
 -PROJ_INFO-------------------------------------------------
 name       : Universe Transverse Mercator
 towgs84    : 0,0,0
 proj       : utm
 ellps      : grs80
 a          : 6378137.0000000000
 es         : 0.0066943800
 f          : 298.2572221010
 south      : defined
 -PROJ_UNITS------------------------------------------------
 unit       : meter
 units      : meters
 meters     : 1.0
 }}}

 and then r.in.gdal segfaults when attempting the matching proj settings
 comparison. (strcmp() missing key value in lib/gis/make_loc.c)
