I have two question:

1. Does the cc compiler is the clone of the acd ?(minix 3)
I found cc,pc,m2 and acd have all the same size of 34020 bytes.
While cc,pc and m2 compile source files, do they all use the
/usr/lib/descr file to guide the compiling?
When should we use the acd ? I didn't see where it is employed.

2. Does the command ln in Minix 3 support symbolic link ?
When i use the '-s' parameter to create a symbolic link,it shows a
error message - 'Function not implemented'.

please help.
