False failure during repeated windows build.

От

Hello.

I found it quite annoying that it stops with complaining as "unused
defines" during repeated execution of build.pl. The subroutine
GenerateConfigHeader prepares %defines_copy before checking the
newness of $config_header and even if it decides not to generate new
one, the following code makes sure if the %defines_copy is empty, then
of course it fails with the message.

The attached fixes that.

regards.

Subject: [PATCH] Fix behavior for repeated build on Windows.

Even after the function GenerateConfigHeader in Solution.pm decided
not to generate a new file, it wrongly checks for the remaining macro
defintions and stops with failure. Fix it by not doing the check if it
skipped file generation.

After commit 9573384 this patch no longer applies, but with a trivial rebase it fixes the issue.

Thanks! This is the rebased version. I'll register this to the next CF.

That's annoying, and you are right.  So, committed.
