No, just NO.

Getting inf or -inf out of floating point actually makes sense: It is not just exactly zero but a whole range of very small numbers which give similar results and are treated as 'limits as x approaches 0'.

Integer numbers and arithmetic are exact and although INT_MAX might be large these days it is still not anywhere near infinity and just does not make any sense at all.
And having signed and unsigned behave differently also does not make any sense at all.
Your compile time option might as well be named '-foutput-random-instructions'

I don't know how many panels you need, but your price sounds ridiculous.
I spend less then a tenth of that and have enough panels for about 2/3 of my electriciy consumption. They are also well on their way to pay for themselves in about 6 years. (currently in year 2).

Unless your build environment is really broken (or you have a seriously a-typicall code base) compile time should not matter nearly as much as the resulting code. Don't forget that the resulting code has a big impact on the test phase of your cycle.

Normally during the edit phase you only touch part of a codebase, and proper dependency tracking should result in only a small part of it being rebuild and linked.
Proper dependency handling is not a job of the compiler.
LInking is also not the job of the compiler. (And untill lld is mature enough llvm and gcc use the same one anyway, and even then it still has to prove itself)

Filtering out nmap to places you don't want it to go is EXACTLY what a firewall is for.
And your IPX comparison is also flawed. You don't need to use your MAC address, that is just one way of generating an IPv6 address. And being able to address a packet to any node on the internet directly is exactly how the internet was suposed to work. (Note that a firewall may still prevent such packet from ariving unwanted).

Or he found a way to sneak in energy without the researchers knowing it.
The problem is that there is still no credible known mechanism for producing or storing it inside the box.

The opinion "Doesn't work" is still valid, but after this one should atleast acknowledge that it is at the very least an ingenious hoax....
