build script perl code strangeness

[Peter Kovacs]

Hi all,

I know perl, but I am not a real expert that knows all possible styles.
The following code looks doubious to me (build.pl line 265).

   provide_consistency() if (defined $ENV{CWS_WORK_STAMP} &&
   defined($ENV{COMMON_ENV_TOOLS}));

I would assume that provide_consistency is always called, and the if 
clause does nothing. What sense has this code?
Or is perl now that smart to read it like a sentence? - Have no hint for 
this. But I rather ask.

Thanks.

All the best
Peter
