re PR fortran/46402 (libquadmath: Add fmalq)
PR fortran/46402 * quadmath.map (QUADMATH_1.0): Add fmaq. * configure.ac: Check for fenv.h, feholdexcept, fesetround, feupdateenv, fesetenv and fetestexcept. * configure: Regenerated. * config.h.in: Regenerated. * quadmath.h (fmaq): New prototype. * quadmath_weak.h (fmaq): Add. * Makefile.am (libquadmath_la_SOURCES): Add math/fmaq.c. * Makefile.in: Regenerated. * quadmath-imp.h: Include config.h. * math/expq.c: Include fenv.h. (USE_FENV_H): Define if libm support for fe* is there. (expq): Add fesetround etc. support if USE_FENV_H is defined. * math/fmaq.c: New file. * libquadmath.texi (fmaq): Add. From-SVN: r168852
