automake is confused by its dependencies files

[Ehud Shabtai]

Hello all,

My project has some include files which has ':' in its path. I.E. some 
C source files has #include ":pt:/inc/c.h".
The automatic dependencies which are generated includes these header files 
and the ':' of the patch causes automake to think that there are 
duplicated targets on the same line.

Is there a way automake can be made aware that these ':' are part of the 
patch and not a rule?

Thanks,

Ehud Shabtai.
