[xml] Bug in Windows makefile?

[Rachael Churchill <rachael churchill linguamatics com>]

The help for configure.js says that "include" and "lib" specify where to 
find the include files and lib files needed to build libxml2, and 
"incdir" and "libdir" specify where the build process should put the 
include files and lib files it has created. The code in configure.js is 
consistent with this, and so is the generated file config.msvc, which 
assigns the input dirs to INCLUDE and LIB, and the output dirs to 
INCPREFIX and LIBPREFIX.

However, I think there's a bug in the makefiles which include 
config.msvc. They say
CFLAGS = $(CFLAGS) /I$(XML_SRCDIR) /I$(XML_SRCDIR)\include /I$(INCPREFIX)
(Makefile.msvc line 47)
and
LDFLAGS = $(LDFLAGS) /LIBPATH:$(BINDIR) /LIBPATH:$(LIBPREFIX)
(line 66).
I think INCPREFIX and LIBPREFIX here should be INCLUDE and LIB, because 
they're supposed to be the input directories, the directories where te 
build process can find the headers and libs it needs.

(INCPREFIX and LIBPREFIX are used correctly later, in the install-libs 
target; the built libs and headers are copied into them.)

Also: I would like to register a vote for allowing spaces in path names 
(in accordance with win32/README.TXT section 1.2 last paragraph). The 
default Visual Studio installation directories (where all the necessary 
libs and headers are) contain spaces. They could be put somewhere else, 
but it would be better not to have to.

Thanks,
Rachael
