Add bits to openlibm headers to switch between using the host headers. 2015-01-09 14:11:11 +01:00			`#ifdef OPENLIBM_USE_HOST_FENV_H`

Rename include/fenv.h to <openlibm_fenv.h>. OpenLibm has an implementation of fenv.h internally. This may be problematic in case you want it to build against the host system's implementation, as it would require you to somehow take the fenv.h file out of the compiler search path. Simply use a different naming scheme, similar to openlibm.h and openlibm_complex.h. If we want to build against the host's fenv.h, we can simply add an '#include <fenv.h>' from within this header. 2015-01-09 13:00:48 +01:00			`#if defined(__arm__)`
Rename the fenv headers. I guess the idea would be to eventually also install all of the openlibm*.h headers, instead of just openlibm.h. Make openlibm_fenv.h suitable for this purpose by moving all of the $ARCH/fenv.h headers next to it. We actually need this change to make OPENLIBM_USE_HOST_FENV_H work. Right now it's still broken, because the "#include <fenv.h>" performed by openlibm_fenv.h still pulls in $ARCH/fenv.h as $ARCH/ is added to the compiler include path. 2015-01-10 10:21:57 +01:00			`#include <openlibm_fenv_arm.h>`
