```nim
type
PFile {.importc: "FILE*", header: "<stdio.h>".} = distinct pointer
# import C's FILE* type; Nim will treat it as a new pointer type
```
This is an excerpt from the Nim manual. In the old Nim versions, it
produces a void pointer type instead of the `FILE*` type that should
have been generated. Because these C types tend to be opaque and adapt
to changes on different platforms. It might affect the portability of
Nim on various OS, i.e. `csource_v2` cannot build on the apline platform
because of `Time` relies on Nim types instead of the `time_t` type.

(cherry picked from commit 8be82c36c9)
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
