+
+ * Make.build: Don't append -ansi to AM_CFLAGS for GCC. Using
+ -ansi changes the behavior of header files significantly. It
+ causes __STRICT_ANSI__ to be defined, and some headers interpret
+ that as cause to e.g. not use `long long' or __attribute__. The
+ former example is bad when off_t is supposed to be `long long',
+ and the latter prevents -Wformat from working.
