Versions: linux-2.6.11-rc4-bk7, gcc4 (GCC) 4.0.0 20050217 (latest fc rawhide from 19Feb DL)
gcc4 cvs seems to dislike "include/linux/i2c.h file":
Error msg: include/linux/i2c.h:{55,194} error: array type has incomplete element type
A. Daplas has recently done a workaround for this on another header file. A thread discussing this
can be found by following the link below:
http://gcc.gnu.org/ml/gcc/2005-02/msg00053.html
The patch changes the array declaration from "struct x y[]" format to "struct x *y".
I realize its only a workaround, but the gcc guys seem to be aware of this.
** Note: I'm a noob at this, so feel free to make chopped liver out of this if its incorrect.
patch below is also attached since I'm not sure formatting survives the cut&paste.
