["friso" <bookie988@xxxxxxx>]

I have followed the instructions exactly on 
http://php.nederland.net/manual/en/install.windows.building.php but I end up 
with this error...

Microsoft (R) Program Maintenance Utility   Version 6.00.8168.0

internal_functions.c
ext\libxml/encoding.h(28) : fatal error C1083: Cannot open include file: 
'iconv.
h': No such file or directory
NMAKE : fatal error U1077: '"cl.exe"' : return code '0x2'

I have tried to configure like this

cscript /nologo configure.js --without-xml

to no avail... can anybody help me out here?
