Compile something invalid, please

[Alpha]

For those of you with 4 or more cores, could you please run this patch through the following test?
Before the patch:

• Run a parallel build, and abort it in the middle (with the abort button)
• Run a parallel build, and make sure a file in the middle of the process contains invalid code so that the build fails

Apply the patch, and repeat the above two steps, comparing how the compiler log has (or has not) changed.

This patch attempts to address strange logging behaviour when a parallel build fails.  (I have, of course, tested it already, however I only have access to dual-core, which may not be enough cores to find possible issues in this patch.)

...before:
Process terminated with status 0 (19 minute(s), 59 second(s))
50 error(s), 710 warning(s) (19 minute(s), 59 second(s))

...after:
Process terminated with status 1 (2 minute(s), 40 second(s))
50 error(s), 706 warning(s) (2 minute(s), 41 second(s))

BTW: These were not really errors...

BTW: These were not really errors...

Those were not, but what I have been observing on my computer is something occasionally such as:
before:

Code

[...]
Process terminated with status 1 (0 minute(s), 0 second(s))
2 error(s), 0 warning(s) (0 minute(s), 0 second(s))
Build log saved as:
file:///home/alpha/dev/cb/src/CodeBlocks-unix_build_log.html

Process terminated with status 0 (0 minute(s), 0 second(s))
2 error(s), 0 warning(s) (0 minute(s), 0 second(s))
Build log saved as:
file:///home/alpha/dev/cb/src/CodeBlocks-unix_build_log.html

after:

Code

[...]
Process terminated with status 1 (0 minute(s), 0 second(s))

2 error(s), 0 warning(s) (0 minute(s), 0 second(s))
Build log saved as: 
file:///home/alpha/dev/cb/src/CodeBlocks-unix_build_log.html

I wanted to make sure that in attempting to resolve this log duplication, I did not create some other problems.
Thanks for testing .  (If you wanted to try to reproduce this bug, it seems to occur more often if after a build fails, you build again without changing anything, so the invalid file is the first to be compiled.)


By the way, seeing something like this is rather confusing to read quickly...

Code

/home/alpha/dev/cb/src/sdk/cbstatusbar.cpp||In member function ‘virtual wxString cbStatusBar::GetStatusTextByPlugin(cbPlugin*) const’:|
/home/alpha/dev/cb/src/sdk/cbstatusbar.cpp|50|error: ‘asdf’ was not declared in this scope|
/home/alpha/dev/cb/src/sdk/cbstatusbar.cpp|51|error: expected ‘;’ before ‘}’ token|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|
||=== Build finished: 2 error(s), 0 warning(s) (0 minute(s), 1 second(s)) ===|

... did the build work?!
