* crt1.c: Revert changes of 2002-04-16. Use _fpreset again.

	* msvcrt.def (_fpreset): Mark as DATA so that only
	_imp___fpreset is exported.

	* msvcrt40.def (_fpreset): Likewise.
	* crtdll.def (_fpreset): Likewise.
	* CRT_fp10.c (_fpreset): Overide library _fpreset with one
	that calls fninit.
	(fpreset): Add oldname alias.
	(__CRT_PC): Delete definition. _fpreset does it now.
	*  CRT_fp8.c (_fpreset): Force use of library _imp___fpreset.
	(fpreset): Add oldname alias.
	(__CRT_PC): Delete definition.
	* moldname.def.in: Comment out fpreset.
	* moldname-msvcrt.def: Regenerate.
	* moldname-crtdll.def: Regenerate.
	* include/fenv.h (FE_DFL_ENV): Define as (fenv_t*)0.
	* mingwex/fesetenv.c (FE_DFL_ENV): Use it to set environment
	with the _fpreset determined by startup CRT_fp object.
