Previously we were defaulting to stdout for diagnostics, which could interfere
with scripts or `nim c -r' programs outputting their results to stdout,
possibly mixing their output with compiler messages.
This change makes now Nim to be inline with other compilers emitting
diagnostics to stderr. Also now --stdout option has proper meaning making all
diagnostics to be sent to stdout instead.
NOTE: Tester now calls compiler with --stdout.
This directory contains the test cases.
Each test must have a filename of the form: ``t*.nim``
Each test can contain a spec in a ``discard """"""`` block.
The folder ``rodfiles`` contains special tests that test incremental
compilation via symbol files.
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. It includes a C
client and platform specific build files for manual compilation.
