Thanks, will check that soon.

Looks good!
As can been seen now, the differences vary up to 36% for exactly the
same commit, making the output completely meaningless, more or less.
Please improve that. A possible solution could be to modify the
benchmark program itself: It should not report 'time per op' but
rather 'cumulative time per N iterations' so that you have access to
more precise values, which can then be used to get better percentages.
Another minor improvement might be to change the table design from
```
Test Baseline Benchmark Difference
------------------------------------------------------------------
Load 5.48 us/op 4.90 us/op 10.61%
Load_Advances (Normal) -5.65 us/op -5.34 us/op -5.40%
Load_Advances (Fast) 23.03 us/op 0.03 us/op 21.21%
```
to
```
Test Baseline Benchmark Difference
(µs/op) (µs/op) (%)
-------------------------------------------------------
Load 5.48 4.90 10.61
Load_Advances (Normal) -5.65 -5.34 -5.40
Load_Advances (Fast) 23.03 23.03 21.21
```
or something similar, thus getting a more horizontally compact layout,
and to better align the numbers vertically. BTW, I still miss the
sentence 'smaller values are better' (or a variation of it) somewhere
at the top.
Another peculiarity in your most recent example HTML page is that some
lines don't have a green field, but the percentage differs. This is a
clear contradiction.
Finally (for today :-), I suggest that you embed a small CSS fragment
at the top of the page (using a `<style>` block) that takes care of
both the table layout and the various colour attributes, avoiding
inline styling (i.e., not using `<td style="...">` but rather `<td
class="...">`).

You must not create the binary directly from the source file.
Instead, you have to create two rules, namely a rule to create the
object file, and another rule that links the object file to the final
binary. For the object file creation you have to use `$(CC)`, and for
the final linking you should use `$(LIBTOOL) --mode=link` in normal
unix build mode, and `$(CC)` otherwise. Have a look into the
`Makefile` of the 'freetype-demos' repository for more details.
