build warnings in source code

[Kralidis,Tom [Burlington]]

Hi,

Compiling latest CVS (04/Nov/2004) on FC2, with 'make clean', then:

./configure --with-freetype=/usr/local/bin/freetype-config
--with-zlib=/usr/local --with-png=/usr/lo
cal --with-jpeg=/usr/local --with-xpm=/usr/local --with-gd=/usr/local
--with-pdf=/usr/local --with-e
ppl --with-proj=/usr/local --with-gdal=/usr/local/bin/gdal-config
--with-ogr=/usr/local/bin/gdal-con
fig --with-postgis=/usr/local/pgsql/bin/pg_config --with-wfs --with-wcs
--with-wmsclient --with-wfsc
lient --without-tiff --with-curl-config=/usr/local/bin/curl-config
[root at devgeo mapserver]# 

...then 'make', most of the build goes okay, but some source code has
some warnings.  None of these are really new, but I thought I'd catch
them all and summarize them to this list.   Most look like simple stuff:

maplegend.c: In function `msDrawLegend':
maplegend.c:233: warning: unused variable `empty_legend'

mapwms.c: In function `msDumpLayer':
mapwms.c:1086: warning: `pszMetadataName' might be used uninitialized in
