-Winline generates warnings against gnulib code

[Reuben Thomas]

Compiling with -Winline, I get warnings like this:

src/main.c: In function 'main':
./lib/gl_xlist.h:124:1: warning: inlining failed in call to
'gl_list_add_last_inline': call is unlikely and code size would grow
[-Winline]
src/main.c:174:35: warning: called from here [-Winline]
./lib/gl_xlist.h:124:1: warning: inlining failed in call to
'gl_list_add_last_inline': call is unlikely and code size would grow
[-Winline]
src/main.c:175:35: warning: called from here [-Winline]
./lib/gl_xlist.h:124:1: warning: inlining failed in call to
'gl_list_add_last_inline': call is unlikely and code size would grow
[-Winline]
src/main.c:176:35: warning: called from here [-Winline]

These are quite reasonable warnings, because the compiler thinks
they're part of my code; but surely gnulib should be treated as system
headers, and -Winline give no warnings. Is there a way to make this
happen?
