True, but we need to move stuff out of osdep.h and into the other files as much as possible, so it is still preferred that you move it. Cheers, Jes

That's a valid argument. As there is more stuff to move out of osdep.h, I suggest doing that in a second step. Now, it is most important to get Windows builds working again (they fail currently with a linker error). > > Cheers, > Jes > Cheers, Stefan

Rather than add it to remove it in the next patch, please update your patch and repost it. That causes less noise and will get win32 building again just as fast. Cheers, Jes

Mingw32 does not provide a declaration and implementation of function setenv (which is used in sdl.c), so this patch adds both. Signed-off-by: Stefan Weil <weil@mail.berlios.de> --- os-win32.c | 15 +++++++++++++++ osdep.h | 2 ++ 2 files changed, 17 insertions(+), 0 deletions(-)
