winpr is now always build as single library.
The build option MONOLITHIC_BUILD doesn't influence this behavior anymore.
The only exception is winpr-makecert-tool which is still build as extra
library.
This obsoletes complex_libraries for winpr.
GetDynamicTimeZoneInformation, SetDynamicTimeZoneInformation and
GetTimeZoneInformationForYear are provided by the Windows SDK accordingly
with ethe MSDN cocumentation for SDK with versions above 7.1A.
Those functions are incorrectly included by the 7.1A SDK if _WIN32_WINNT
>= 0x0501 instead of _WIN32_WINNT >= 0x0600.
The issue arises when building with an XP compatible toolset (e.g.
v120_xp).
