[ccache] Issues using ccache

[NITIN KHOSLA, BLOOMBERG/ 731 LEXIN]

I am using first time. I have read documentation but not found my answers.
Simple command: ccache gcc -o 1.o 1.c
ccache -V
ccache version 3.1.4

a) Ran first time and then second time. What called for link means?
   called for link                        1
   called for link                        2

   It should find it from cache second time. It did not.
   cache hit (direct)                     0
   cache miss                             0

b) I created a ccache log file(log below is same for exactly same above mentioned gcc command called multiple times). :

c) Running with solaris compiler (CC) somewhere calls ccfe. And for that, ccache says 
"unsupported source language            1"

Can someone please comment or let me know if I am doing something not right?

thank you all,
Nitin
