Compiling under Windows from the commandline in /winbuild with
USE_IDN=yes fails with unresolved externals _IdnToAscii and
_IdnToUnicode.

Solution: add /DWANT_IDN_PROTOTYPES to line 175 of MakefileBuild.vc in
winbuild

-CFLAGS = $(CFLAGS) /DUSE_WIN32_IDN
+CFLAGS = $(CFLAGS) /DUSE_WIN32_IDN /DWANT_IDN_PROTOTYPES

WANT_IDN_PROTOTYPES is needed in /lib/idn_win32.c

As a background my nmake commands, executed in /winbuild
C:\php-sdk\curl-src\winbuild>nmake /f makefile.vc mode=static VC=9 \
                        WITH_DEVEL=../../win32build MACHINE=x86 \
                        USE_IDN=yes WITH_SSH2=static WITH_ZLIB=static
or
C:\php-sdk\curl-src\winbuild>nmake /f makefile.vc mode=static VC=9 \
                        WITH_DEVEL=../../win64build MACHINE=x64 \
                        USE_IDN=yes WITH_SSH2=static WITH_ZLIB=static

C:\php-sdk\win32build and C:\php-sdk\win64build contain the /include and
/lib dependent files for x86 and x64.

Combining SSL and SSH2 is a story for another post.
