This is informational for people who might be building perl 4.0 on FPS Model 500 series computers. I just built 4.010 on an FPS Model 500 with FPX 4.3 and I didn't use the FPS defaults and the program built and passed all of it's regression tests just fine. The only thing I changed with Configure was to align doubles on 8 bytes boundaries rather than 4. This is not absolutely necessary but non-8-bit-aligned doubles can be a serious performance hit. The fps defaults supplied with Configure were to set the additional CFLAGS to "-J -DBADSWITCH". I don't think -J has been needed since the Celerity 1260D (predecessor to the FPS Model 500) and I don't know where the -DBADSWITCH came from. I assume that since it's a known problem that the regression tests would catch if you needed -DBADSWITCH. Maybe some time in the next week or so I'll try to get it running on a C1260 to know for sure. I won't post about it unless I get more than 2 responses from people with old 1260's who care to know how it went. We don't have any real perl hackers around here that I know of so I can't really beat on it more severely than the regression tests (but I'm working on it in my "spare time"; where's that man "page" ;-). --Bill Davidson
