ActiveState's ActivePerl 5.16 (and earlier) is available only with their Business and Enterprise Editions (i.e., it is no longer freely available for download from their website).

I'm currently using 5.18 so Sereal is unavailable (ditto for 5.20). Sigh.

... stuff ...

Um, yeah, when BrowserUk says "not for win32" a lot of the time he says "its not on ppm" cause the version that is on ppm is very old and/or not available to everyone

luckily, you can "strawberryperl" your activeperl by installing http://code.activestate.com/ppm/MinGW/ ... and then you should be able to compile Sereal just as if you were using strawberry perl .... Maybe

OTOH, you can always install strawberryperl :)

Not so:

Basically, the source files are not C language compliant: You cannot have declarations after executable statements within a block.

It seems that gcc allows this, but I don't use gcc, so.

(I'd also say that having been forced to inspect the code; I see no reason to trust this code more than Storable, and quite a few reasons to trust it less. IMO: Any C programmer who ignores that many warnings, is like a Perl programmer who doesn't use strict or warnings.)
