some problems in dmd.2.034

[zsxxsz]

I'll download the new release dmd2.xxx where the new one was released. But
when I compile dmd2.xxx, I always encounter the same problem as below:
$cd dmd.2.034/dmd2/src/dmd
$make -f linux.mak

backend/dwarf.c:54:26: ../mars/mars.h: No such file or directory
backend/dwarf.c: In function `void dwarf_initfile(const char*)':
backend/dwarf.c:447: error: `global' was not declared in this scope
make: *** [dwarf.o] Error 1

g++ -m32 -c -Wno-deprecated -D__near= -D__pascal= -fno-exceptions -O2
-Ibackend -Itk -D__I86__=1 -DMARS=1 -DTARGET_LINUX=1 -D_DH backend/dwarf.c
In file included from backend/dwarf.c:54:
backend/../mars/mars.h:246:25: complex_t.h: No such file or directory
make: *** [dwarf.o] Error 1

I have to do as below:
$mkdir mars
$cp mars.h mars/
$cp complex_t.h mars/

and continue to make -f linux.mak, then the compiling will be finish.
The problem appeared in DMD.2.xxx, including DMD.2.034. And then, in
DMD.2.034, there is a new problem when compiling druntime as below:
$cd dmd.2.034/dmd2/src/druntime/src
$ make -f dmd-posix.mak
