Due to a very high time precision on certain filesystems the chance of a failing compilation increases because make keeps on regenerating doc.c key.c funs.h. The attached patch reorders the must_fopen and fclose calls in info/makedoc.c such that the times associated with these files match the dependencies specified in the Makefile.*. Please comment on the patch to verify its correctness. -- Fabian Groffen Gentoo on a different level
