[Message part 3 (text/plain, inline)]

Hello,

compiling sed from git (v4.2.2-89-ge387009) fails with gcd-5.2 due to -Wunused-macros (and -Werror):

===
make[3]: Entering directory `/home/gordon/sources/sed/sed'
  CC       compile.o
compile.c:36:0: error: macro "OPEN_BRACE" is not used [-Werror=unused-macros]
 #define OPEN_BRACE '{'
 ^
compile.c:183:0: error: macro "END_ERRORS" is not used [-Werror=unused-macros]
 #define END_ERRORS (INCOMPLETE_CMD + sizeof(N_("incomplete command")))
 ^
cc1: all warnings being treated as errors
make[3]: *** [compile.o] Error 1
===

The attached patch comments-out the two macros. Alternatively they could be simply erased.

regards,
 - assaf

P.S.
I don't yet have copyright assignment for sed, but I think this change is trivial enough.

[sed-unused-macros.patch (text/x-diff, attachment)]

Thank you. I've pushed that with slight tweaks to the commit log.
