Compile error in ADRG

[vanlaake@…]

During make of OSSIM with g++ 2.95.3 I get the following:

...
make[5]: Entering directory
`/big/tar/ossim-0.2.0a/src/util/image_proc/formats/adrg'
/usr/bin/g++ -Wall -fPIC -O2  -c ADRGTileSource.cc
ADRGTileSource.cc: In method `ADRGTileSource::ADRGTileSource(const adrg_zdr *)':
ADRGTileSource.cc:88: assignment to `adrg_zdr *' from `const adrg_zdr *'
discards qualifiers
make[5]: *** [../../../../../lib/libossim.a(ADRGTileSource.o)] Error 1
...

I commented out the all: section in the Makefile and the reference to ADRG in
src/util/image_proc/factory/TileSourceFactories.h after which a new make ran
fine. I presume I have to go through life without ADRG support now .... (sigh)
