Not present or too old. For such machines I don't want Xft, so that
the X server (normally a faster machine with redirected DISPLAY)
renders the fonts.

I have got it working on HP-UX, see Github issue 937.

I have run the bitmap test (Github issue 449) on the HP machine (32-bit
HPPA) and the image looks good.

Based on the HP-UX patchset, I have tried to get it compiled with egcs.
With some more patches it was possible. I will open a separate Github
issue for egcs.

Sooner or later I should repair it anyway, but not this weekend.

No problem here too. snprintf() is in SUSv2, commercial UNIX
variants should support it.

Nanosvg seems to be C code that use C++ comments.
