Hello,

encountered this insufficiency several times while investigating bugs in
several .NET/managed apps:

The missing iphlpapi export seems not critical for functioning of apps (first
chance exception is caught) but it's better to fill holes in wine's API.

MSDN info here: http://msdn.microsoft.com/en-us/library/aa365915.aspx

Set component as -unknown- because iphlpapi component doesn't exist in
bugzilla.

(NOTE for myself: encountered this in VS.NET 2005 startup phase, under managed
debugger, 'ca e')
