Btw,
lang/fpc-devel (and to a lesser degree lang/fpc) are not libc_r dependant
themselves, but generate libc_r programs when language threading is used.
I'll fix this in the coming weeks, but rather like to do this runtime.
How can I detect (in a non C/libc program, iow without using headers or
libraries, so in the general FreeBSD environment), whether I should pass
-lc_r to the linker or -lc -lpthread ?
(sysctl or uname based solutions come to mind)
If this isn't possible I'll use a compile conditional and test the freebsd
version in the port Makefile, but I prefer runtime detection if doable.
