Yes, this fixes the problem in this case (besides some macro
redefinition warnings).

Unfortunately, it makes another compile error in svg.c visible:
D:\project\PLPlot\drivers\svg.c(341) : error C2143: syntax error :
missing ';' before 'type'
I'll take a look at that.

A build with BUILD_SHARED_LIBS=ON gets problems at the same location (in
unmodified rev8861):
cl -Dplplotd_EXPORTS /DWIN32 /D_WINDOWS /W3 /Zm1000 /D_DEBUG /MDd /Zi
/Ob0 /Od /RTC1 -ID:\project\PLPlot\include
-ID:\project\PLPlot\build-vc9-shared-Debug
-ID:\project\PLPlot\build-vc9-shared-Debug\include -DHAVE_CONFIG_H
-D_CRT_SECURE_NO_DEPRECATE /FoCMakeFiles\plplotd.dir\__\drivers\hpgl.obj
/FdD:\project\PLPlot
\build-vc9-shared-Debug\dll\plplotd.pdb -c D:\project\PLPlot\drivers\hpgl.c
hpgl.c
D:\project\PLPlot\drivers\hpgl.c(141) : error C2375:
'plD_dispatch_init_hp7470': redefinition; different linkage
D:\project\PLPlot\include\drivers.h(73) : see declaration of
'plD_dispatch_init_hp7470'
Adding the snippet
#define STRINGIZE2(x) #x
#define STRINGIZE(x) STRINGIZE2(x)
#pragma message ("PLDLLEXPORT" STRINGIZE(: PLDLLEXPORT))
#pragma message ("PLDLLIMPEXP" STRINGIZE(: PLDLLIMPEXP))
to hpgl.c (in otherwise unmodified rev8861) shows that for
BUILD_SHARED_LIBS=ON PLDLLEXPORT expands to __declspec(dllexport), but
PLDLLIMPEXP stays empty.
Further investigation shows that MAKINGPLDLL is not defined when
compiling hpgl.c.
