Doh!  It's nothing to do with name mangling -- the problem is much 
simpler than that!  win32_malloc etc are not MS C runtime functions at 
all -- they're defined in Perl's win32/win32.c.  (The __imp__ decoration 
just means that the linker is looking for these functions in a DLL's 
import library.)  The problem was simply that no Perl library is being 
linked against!

I re-ran parrot's Configure.pl like this:

perl Configure.pl "--ccflags= :add{ -I../../perl -I../../perl/win32 
-I../../perl/win32/include}" "--linkflags= :add{ 
-LIBPATH:C:/perl/lib/CORE}" "--libs= :add{ perl59.lib}"

and now parrot builds OK.  Is this right?  I'm using the non-ponie-perl 
there, of course, because I haven't built the ponie one yet...

Now onto building the Perl part of Ponie...

I had to hack the win32/Makefile to put parrot's include and lib 
settings in place:

INCLUDES    = -I$(COREDIR) -I.\include -I. -I.. -I..\..\parrot\include
LIBFILES    = $(LIBBASEFILES) $(LIBC) libparrot_s.lib
LINK_FLAGS    = -nologo -nodefaultlib $(LINK_DBG) \
        -libpath:"$(INST_COREDIR)" -libpath:..\..\parrot\blib\lib \
        -machine:$(PROCESSOR_ARCHITECTURE)

I then got some warnings out of the linker when building miniperl.exe:

        link -subsystem:console -out:..\miniperl.exe 
@C:\DOCUME~1\steveh\LOCALS~1\Temp\nma02956.
   Creating library ..\miniperl.lib and object ..\miniperl.exp
LINK : warning LNK4049: locally defined symbol "_win32_malloc" imported
LINK : warning LNK4049: locally defined symbol "_win32_abort" imported
LINK : warning LNK4049: locally defined symbol "_win32_printf" imported

(this must be related to the linker problems that I had above when 
building parrot), but sadly the build failed later on when compiling 
perllib.c:

        cl -c -I. -nologo -Gf -W3 -I..\lib\CORE -I.\include -I. -I.. 
-I..\..\parrot\include -DWIN32 -D_CONSOLE -DNO_STRICT -DHAVE_DES_FCRYPT 
-DPERLDLL -DPERL_CORE   -MD -DNDEBUG -O1  -DPERL_IMPLICIT_CONTEXT 
-DPERL_IMPLICIT_SYS -DUSE_PERLIO -DPERL_MSVCRT_READFIX -TP -GX 
-Foperllib.obj perllib.c
perllib.c
..\..\parrot\include\parrot/interpreter.h(59) : error C2040: 
'Parrot_Interp' : 'struct Parrot_Interp *' differs in levels of 
indirection from 'struct Parrot_Interp'
..\lib\CORE\intrpvar.h(535) : error C2079: 'IParrot' uses undefined 
struct 'Parrot_Interp'
NMAKE : fatal error U1077: 'cl' : return code '0x2'
Stop.

The second error is presumably a consequence of the first; the first 
must be something that the MSVC++ compiler doesn't like.  interpreter.h 
line 59 is this:

typedef struct Parrot_Interp *Parrot_Interp;

How can I get around this problem?
