[fpc-pascal] CThreads for linked C library?

[Johann Glaser]

Hi!

libusb(x) links to libpthread:

$ ldd /lib/x86_64-linux-gnu/libusb-1.0.so.0
	linux-vdso.so.1 => 
	librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
	/lib64/ld-linux-x86-64.so.2

If I'm linking to libusb(x), the resulting executable also links to
libpthread.

Looking at the libusbx source code (and API documentation) reveals, that
they don't use threading, they only use the mutexes (pthread_mutex_*)
and condition variables (pthread_cond_*).

Is it necessary to have the unit "CThreads" in my Uses clause?

Thanks
