+From: "P. J. McDermott" <pjm@nac.net>
+Description: Fix empty awk function
+ gcc/config/i386/i386-builtin-types.awk defines and calls a function named
+ "attribute_mode" with zero statements.
+ .
+ BusyBox awk prints the following error message when building GCC:
+ .
+ awk: …/gcc/config/i386/i386-builtin-types.awk:164: Call to undefined function
+ .
+ This seems to be due to lines 2664 and 2665 of editors/awk.c in BusyBox 1.21.0,
+ which throw a syntax error if the called function has no nodes in its node
+ chain:
+ .
+ if (!op->r.f->body.first)
+ syntax_error(EMSG_UNDEF_FUNC);
