A possible reason why this hasn't been a problem for others is that I'm using a 'technology preview' of MinGW from 2007 which comes with GCC 4.2.1, instead of the stable 3.4.5 from 2006. My `winnt.h` contains the following (snipped down to size where irrelevant): {{{ #if (__GNUC__ >= 3) /* Support -masm=intel. */ static __inline__ PVOID GetCurrentFiber(void) { ... } ... #else /* __GNUC__ >= 3 */ static __inline__ PVOID GetCurrentFiber(void) { ... } }}} So it seems that with a recent enough version of these headers the fiber functions get defined in any case, regardless of compiler version; were people to grab the latest version of [http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=11550 w32api] they'd run into these problems as well. Judging from the file timestamps I've got 3.11, the second-newest. 3.12's `winnt.h` appears identical in this respect, so updating wouldn't help. Since the two lines are claimed to be only for warning avoidance, I suggest just removing them." merge closed normal 6.10.2 Runtime System 6.11 fixed Windows x86 Unknown
