Unused local typedef
When building with gcc 4.8.2, this error appears:
In file included from /dpool/export/home/mills/Downloads/code/illumos-gate/proto/root_sparc/usr/include/fcntl.h:40:0,
../screen/tgetch.c: In function '_fpk':
/dpool/export/home/mills/Downloads/code/illumos-gate/proto/root_sparc/usr/include/sys/fcntl.h:213:3: error: typedef 'flock_t' locally defined but not used [-Werror=unused-local-typedefs]
The solution is to remove the unused local typedefs. For gcc 4.8.2, the error can be suppressed by adding this line to Makefile or Makefile.com, with the group of similar lines:
CERRWARN += -_gcc=-Wno-unused-local-typedefs
This error occurs in two locations: usr/src/lib/libnsl/sparc and usr/src/lib/libcurses .

you could perhaps add instead on the typedef
instead of the CERRWARN.
I'm curious, though, as to whether you see the warning if you move the
to global scope (outside of _fpk or even top of file in tgetch.c)...

Yes, moving the include statement fixed the problem. They must have been economizing on conditionals. There were actually two files affected: ../screen/tgetch.c ../screen/typeahead.c . I moved the include statements to the top and wrapped them in appropriate conditionals. Then I no longer needed to add `-_gcc=-Wno-unused-local-typedefs' to Makefile.com to suppress the error. I'm attaching both new patch files.
