Fehlermeldung Atmel Studio cannot find -l

Moinsen,

folgendes Problem in Atmel Studio 7.0:

Beim Linken findet avr-gcc.exe die Libraries nicht (cannot find 
-lcmd.h), obwohl diese im Verzeichnis sind 
(H:\foo\TSW\AtmelStudio\cmd.h) und das Verzeichnis in den Optionen 
angegeben ist (-Wl,-L"H:\foo\TSW\AtmelStudio")
Der Compiler findet alle.

Es funktionierte jahrelang mit Make auf WinAVR. Nach Update auf Windows 
10 funzte das Make mit WinAVR nicht mehr. sh.exe hatte ein Problem mit 
cygwin.

Bei der Umstellung auf die AS-Toolchain nun o.g. Problem.

Hat jemand eine Idee dazu?

mny tnx
