linux - Figuring out __only_inline C macro used on BSD -


i'm trying port openbsd make linux i'm confused use of __only_inline macro. macro comes /usr/include/sys/cdefs.h defines follows:

/*  * __only_inline makes compiler use function definition  * inlining; references can't inlined left  * external references instead of generating local copy.   * matching library should include simple extern definition  * function handle references.  c.f. ctype.h  */ #ifdef __gnuc__ #  if __gnuc_prereq__(4, 2) #define __only_inline   extern __inline __attribute__((__gnu_inline__)) #  else #define __only_inline   extern __inline #  endif #else #define __only_inline   static __inline #endif

can explain purpose of macro? it's used in openbsd make in targ.h:

http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/make/targ.h?rev=1.13&content-type=text/x-cvsweb-markup

isn't comment clear enough? __only_inline definition used can inlined. definition must exist somewhere else uses cannot inlined.

you might want have @ bmake netbsd/pkgsrc. similar make has been autoconf'ed , portable gnu/linux. can find latest version here: bmake

in general though can ignore entirely (i.e. remove it), or convert extern inline.

if email marc can tell why used in case.
