I'm in the middle of configuring 5.5.64 right now and I noticed the following little burp​:

Guessing which symbols your C compiler and preprocessor define... :2​: warning​: `#ifdef' argument starts with a digit :7​: warning​: `#ifdef' argument starts with a digit Your C compiler and pre-processor define these symbols​: i386 unix

Is this a problem? I don't have nearly enough masochistic knowledge of Bourne Shell to attempt to understand what's going on in Configure.

These can be safely ignored. (It's testing if you're on a 3B1\, for example. Even I don't have one of those running anymore. (The last perl5 I built on one was probably 5.001e or so.)

Don't bother. Jarkko's rewritten the underlying unit anyway\, so 641's version will look rather different\, I expect.
