Hmm. K.3.3.1 of [1] says you can show or hide all that _s stuff by defining that macro to 0 or 1 before you include <string.h>, but it's implementation-defined whether they are exposed by default, and the template file is one way to deal with that implementation-definedness... it's not quite in the autoconf spirit though, it's kinda manual. Another approach would be to define it unconditionally at the top of explicit_bzero.c before including "c.h", on all platforms. The man page on my system tells me I should do that anyway, even though you don't need to on my system.
Why is your Solaris system trying to compile that file in the first place? A quick check of the Solaris and Illumos build farm animals and some online man pages tells me they have explicit_bzero(). Ahhh... looks like it came a few years ago in some Solaris 11.4 update[2], and Illumos (which forked around 10) probably added it independently (why do Solaris man pages not have a history section to tell us these things?!). I guess you must be running an old version. OK then.
