dup2: clarify by coalescing Windows-specific material * lib/dup2.c: Move '#include "msvc-inval.h"' and '#include "msvc-nothrow.h"' to the Windows-specific section, so that the Emacs source need not contain these include files. (ms_windows_dup2): Rename from dup2_nothrow, and move all the Windows-specific fixes into this function rather than just the nothrow fix, as this shortens and clarifies the code. Always define as a function, as that's a bit cleaner than having it be sometimes a function and sometimes a macro. (rpl_dup2): Move the Windows-specific stuff out of here and into ms_windows_dup2. Don't protect the Haiku-related fix with "#if !defined __linux__", as the same code also works around a Linux kernel bug, and it doesn't add any system calls on any platform. Add comment about FreeBSD 6.1.
