[Click] Configure and timespec

[Roberto Riggio]

  Hi,

this is not actually creating any problem to me. I'm reporting it just 
in case it may
prove useful. Lurking in the configure.log, I've found the following error:

configure:7464: checking for struct timespec

configure:7464: result: yes

It looks like albeit the compilation fails, the configure reports that 
timespec
is actually available.
