So, what do you suggest how I should solve the problem instead? If your
suggestion is "change the C library" then I can tell you upfront that I
don't have that choice...
Are you even against adding the patch I posted, i.e. to have it fully
contained within cairo-os2-surface.c?
And about the different free function: in the cases that I have pointed
out (I could give more detail) there is always a function that allocates
stuff and a corresponding function that frees stuff. So it's not like
for those allocations I would need to add the DosAllocMem() in one file
and the corresponding DosFreeMem() in another one or even worse several
 One other possibility would be to use C library functionality to
create additional heaps, but that would need even more lines and be
way more ugly...
