Keys in enum are case-sensitive on OSX and case-insensitive on linux #21207
Description
Description
On OSX the keys in an enum are case-sensitive, while on linux they are case-insensitive
On OSX the following executes without error:
# uname -a; echo "type Key* = enum Key_A, Key_a" >/tmp/test.nim && nim cpp /tmp/test.nim
Darwin (hostname) 21.6.0 Darwin Kernel Version 21.6.0: root:xnu-8020.240.14~1/RELEASE_X86_64 x86_64
On linux it gives an error:
# uname -a; echo "type Key* = enum Key_A, Key_a" >/tmp/test.nim && nim cpp /tmp/test.nim
Linux (hostname) 5.15.0-56-generic #62-Ubuntu SMP Tue Nov 22 19:54:14 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
/tmp/test.nim(1, 25) Error: redefinition of 'Key_a'; previous declaration here: /tmp/test.nim(1, 18)

### Current Output
_No response_
### Expected Output
```text
I assume that the keys in an enum should always be case-insensitive, hence for OSX I would expect also an compilation error.
Possible Solution
No response
