Trying to compile dcmtk-341 on MacOSX Server

Machine:  Power Macintosh G4
OS:       MacOSX Server 1.2  (Rhapsody 5.6)
Compiler: gcc-2.7.2.1

* Step 1:
	cd config
        ./rootconf
        cd ..

	No problem here

* Step 2:
        ./configure

	Apparently no problem here as well

* Step 3:
        make all

	- leads to:

(cd apps; make ARCH="" all)
c++     -DHAVE_CONFIG_H  -DNDEBUG  -c -I. -I. -I../include -I../../config/include -I../include -I../../ofstd/include -I../../dcmdata/include  \
         -g -Wall  ./dconvlum.cc 
c++ -g -Wall   -L../libsrc -L../../dcmdata/libsrc -L../../ofstd/libsrc -L/usr/local/dicom/lib -o dconvlum ./dconvlum.o -ldcmimgle -ldcmdata -lofstd -lm -lg++   
/usr/bin/ld: can't locate file for: -lm
make[2]: *** [dconvlum] Error 1
make[1]: *** [apps-all] Error 2
make: *** [dcmimgle-all] Error 2

	Hmm, CHANGES.340 says this:
	- Linking -lm to dcmimgle/apps, required on OSF1.
	  Affects: dcmimgle/apps/Makefile.in

	-> change in dcmimgle/apps/Makefile.in
	#LOCALLIBS = -ldcmimgle -ldcmdata -lofstd -lm
	# bk20000508: removed -lm for MacOSX
	LOCALLIBS = -ldcmimgle -ldcmdata -lofstd

* repeat Step2, 

* Step3
	make all

	- leads to:

* repeat Step2

* Step 3
	make all

	- leads to:

c++     -DHAVE_CONFIG_H  -DNDEBUG  -c -I. -I. -I../include -I../../config/include -I../../dcmpstat/include -I/usr/local/dicom/include/dcmpstat -I../../ofstd/include -I/usr/local/dicom/include/ofstd -I../../dcmnet/include -I/usr/local/dicom/include/dcmnet  -I../../dcmdata/include -I/usr/local/dicom/include/dcmdata -I../../dcmimgle/include -I/usr/local/dicom/include/dcmimgle -I../../imagectn/include -I/usr/local/dicom/include/imagectn  \

make[2]: *** [dcmprtsv.o] Error 1
make[1]: *** [apps-all] Error 2
make: *** [dcmpstat-all] Error 2

	The problem seems to be that dcmprtsv.cc directly includes /usr/include/dirent.h
	without having included the correct types.h

	-> change in dcmpstat/apps/dcmprtsv.cc

	#include "osconfig.h"    /* make sure OS specific configuration is included first */
	/* bk20000508: this makes sure the correct types.h is included (was needed for inclusion of <dirent.h>) */
	#include "dcompat.h"

	=> "make all" succeeds

All tools seem to work (tested imagectn, storescu, storescp, echoscu, dcmdump, dump2dcm). 

Note: The default endianness on the Mac is BigEndianExplicit. It might be good to force LittleEndianImplicit...
