Sorry for repeating myself. I have experienced some problems with the fat filesystem module (see another thread "Segmentation Fault when accessing partition") from kernel.org 2.6.10 sources. Therefore I have been trying to compile the kernel-2.6.10-1.766_FC3 sources. However I receive errors like fs/freevxfs/vxfs_kcompat.h:6:25: operator '<' has no left operand unselecting the filesystem results in similar errors for jffs2 and apm modules. I'm using gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3) Using the same compiler on the kernel.org sources results in no compilation errors. Is it a bug or is there something I can do? Thanks Torben
