        <pre>Function setRGB is first declared as inline, then defined as inline, and then
not found by the linker.

$ clang -I/usr/local/include -lm -L/usr/local/lib -lpng -o makePNG makePNG.c
/tmp/makePNG-3638e2.o: In function `writeImage':
makePNG.c:(.text+0x6e8): undefined reference to `setRGB'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Removing 'inline' attribute fixes the compile.
This problem is particularly bad due to the simplicity of this situation.

The testcase is from this book:
<a href="http://www.labbookpages.co.uk/software/imgProc/libPNG.html">http://www.labbookpages.co.uk/software/imgProc/libPNG.html</a>
Particular failing program:
<a href="http://www.labbookpages.co.uk/software/imgProc/files/libPNG/makePNG.c">http://www.labbookpages.co.uk/software/imgProc/files/libPNG/makePNG.c</a>
(The only change I made is replaced malloc.h -> stdlib.h)

gcc compiles it successfully.

Observed in rev.217271 on FreeBSD 10</pre>
