When I try to build DMD revision 575 in debug mode on my Linux machine I get
this error:

cgcv.o: In function `cv4_outsym':
/mnt/sharedhd/dprojects/experimental/properties/dmd.svn.r575/src/backend/cgcv.c:2277:
undefined reference to `obj_long(int, unsigned int, unsigned long, unsigned
int, unsigned int, unsigned int)'
collect2: ld returned 1 exit status
make: *** [dmd] Error 1

It seems to be caused by the removal of obj_long in elfobj.c at revision 572.  

I'm not sure what the proper way to fix it is since obj_long seems to be on its
way out from elfobj anyways.  As a workaround I just put the stub back from
pre-r572 to make it compile.

I compiled DMD in debug mode by switching to this GFLAGS line in linux.mak:
GFLAGS = $(WARNINGS) -D__near= -D__pascal= -fno-exceptions -g -DDEBUG=1
-DUNITTEST $(COV)

When I compile with the normal GFLAGS everything works fine.

My Linux machine is 64-bit but I am building the 32-bit version of the compiler
like normal.
