janwas a915bdc1b6 fix problems related to 64-bit compilation in lib
. dbghelp is now pulled in by a separate external_libraries header
. disable _SECURE_SCL (improves perf)
. amd64: initial implementation of essential functions, not yet complete
. manifest: disabled on ICC because its IPO module incorrectly
interprets /manifestdependency
. wdbg_sym: no longer support stack walks on non-ia32 win2k (avoids
trouble due to mixing SEH and dtors)
. winit and wstartup: had to remove forced symbol include - does not
link otherwise on ICC (for reasons unknown). function pointers are
actually included and called on x64 windows (compiling with MSC)

This was SVN commit r5895.
