Here's another reason - cross-platform availability.
FPC is cross platform. To some extent (Java?) is more cross-platform that C
is.

When using an external library, there might be a risk that the library is
not *easily* available for another platform that is targeted. It's common
for open-source projects, not to provide any binary builds, requiring a
library user to build the library themselves. Luckily, the most common
projects do have some satellite projects that actually provide binaries.

Building C (C++) library could be a real pain for some Pascal users.
(Pascal spoils!)
Building C/C++ library for a desired target platform, could be even more
painful, specifically if some sort of cross-tools required or when building
configuration needs to be changed.

Thus a pure pascal library would be a number one choice for most users.
With though it might be outdated and/or slower than its C-counterpart (i.e.
paszlib vs zlib)

thanks,
Dmitry
