…not available

According to the comment for primitiveFileStdioHandles():

Answer an Array of file handles for standard in, standard out and standard error, with nil in entries that are unvailable, e.g. because the platform does not provide standard error, etc.

However, on Windows in practice an array of sqFile entries with null handles is returned. The image is unable to distinguish between valid and invalid entries since sqFile is private to the VM.

- Modify sqWin32FilePrims.c() to set the valid mask correctly. - Modify primitiveFileStdioHandles() to treat a mask of 0 as successfully determining that no stdio is available (a normal case on Windows). A validMask of -1 is treated as an error. - Update comments to reflect changed behaviour You can view, comment on, or merge this pull request online at:
