Problem Building mcf5206elite BSP under Cygwin - Workaround Found

I just got a successful build!!! (OK, maybe it isn't that exciting, but after you spend days beating your head against the wall...)
I first verified that the "build_alias" error occurred at different places in the build process at different times, even when opening a new cygwin console and running EXACTLY the same sequence of commands each time. (In other words, something in the environment was inconsistent). On a hunch, I tried disabling my virus scanner's "file system real time protection" (it is Symantec AntiVirus Corporate Edition V8.1.0.825) and it built successfully. I still don't know why disabling the virus checker made a difference, but at least I have a way to get it to build now.
I have tried leaving the virus checker enabled but excluding the cygwin directory tree; that doesn't seem to work. So the only workaround I know of at the moment is turning the real time protection completely off when rebuilding RTEMS. It doesn't report finding any viruses (no false positives as far as I can tell).
I don't have the expertise to troubleshoot the interaction between Symantec AntiVirus, Cygwin and the RTEMS build system, so I won't be able to submit any patches for the problem. If someone else wants to look into it, I will be glad to test. For the record, I was able to build the mcf5206elite BSP using 4.6.0pre4 tools on about 8-22-2003 with the virus checker enabled and unable to with either that version or 4.6.0pre5 for the last week or so. In between those dates, my cygwin setup was updated several times and the virus checker may have been as well (it does automatic updates), so I don't know which thing that changed made the difference.
Thanks everyone for your suggestions,
Steve

It seems that the dependency checks that make does don't realize that it failed, and sometimes go on to the next stage.

>To summarize, I think my shell has been bash all along. My consistent problem is that make fails with a "build_alias" error at some point. Where that point is varies, and when I run make again after a failure, what it does next varies. I am starting to think that there is something wrong with my cygwin installation. I will try updating it and repeating the process. Any other ideas of what to try would be greatly appreciated. Thanks.

I had trouble building it with 4.6.0pre4 a week or so ago, then had to take a break to work on a different project. 4.6.0pre5 was released in the meantime, so when I got to come back to this project, I downloaded the new tools and RTEMS source and started over.
