Can't Install KDE

[Barry Skidmore]

When doing a make on kde3 in ports on 4.9-RELEASE, I get stuck in the
following install loop.  I have looked at the file 'cdefs.h', and there
are many references to `_POSIX_C_SOURCE', all of which are commented
out.  Can I assume that I should uncomment lines 273 and 279?  I have
attached 'cdefs.h'.
