Please write a GNU autotools detection mechanism to test for `grep` on the target system, and if grep is present, detect it's capabilities to support EREs, PCREs, and the correct command line switches to put grep into that mode.

As autotools traditionally tests systems and/or tools for their support for individual features, to see if they are properly supported. My suggestion would be to test the grep command in four phase:
1. Including any possible shell builtins, find all grep variations (including`grep`, `egrep`, `fgrep`, etc.) that are defined or installed in the current shell path.
2.  Enumerate all modal "production features" (not features like `--help` as it is intended as a user/developer aid, and not intended to be used within a script) and any command line flags/switches that have been used to enable them in any popular versions of grep, then determine which switches each version of grep variation recognizes and/or allows without generating an error. Ideally I would prefer to identify a long and sh
