I installed gcc-2.7.2 and tried to compile the 1.2.13 kernel and received the following error: /usr/src/linux-1.2.13/include/asm/io.h:82: inconsistent operand constraints in an 'asm' This kernel works fine with gcc-2.6.3. Has anybody seen this before, what's happening here? Any help/pointers in the right direction would be greatly appreciated. wendal
