Gcc_flag issue with Max os

[xjing76]

Does it make sense to add in the flag settings by default to avoid the issue with Mac?
I have to set those flag manually every time I set up a new environment on Mac.

aesara.config.warn_float64 = 'ignore'
aesara.config.gcc__cxxflags = "-Wno-narrowing"

The underlying issue is aesara-devs/aesara#127. We need to merge the associated PR: aesara-devs/aesara#972.

Thanks for reporting it; we'll do that ASAP (ideally before we forget again).
