Are you using evil macros?
Compile with -H to get the include hierarchy.
Compile with -E -.i then look at grep.i to see what's going on with macros on line 104.

error #2020: identifier "PACKAGE_BUGREPORT" is undefined
error #2020: identifier "STDOUT_FILENO" is undefined
error #2020: identifier "PACKAGE_STRING" is undefined

Where should these be defined?
The middle one is indirectly from .

"grep.c" from where? Which "cc"? On what?

If this is part of a GNU "grep" kit, then you
might do better if you followed the
installation instructions (normally in
"INSTALL"), normally something like:

./configure
make

Otherwise, you might look for a pre-built kit
(depot) for your (undisclosed) OS.
