>Description:
	When preparing the next version of ports/french/aster, with MUMPS
	support, which requires gfortran and gcc41, I'm stuck with an
	error in <fenv.h>:

	In file included from inisig.c:108:
	/usr/include/fenv.h: In function 'inisig_':
	/usr/include/fenv.h:112: error: invalid storage class for function 'feclearexcept'
	/usr/include/fenv.h:133: error: invalid storage class for function 'fegetexceptflag'
	/usr/include/fenv.h:150: error: invalid storage class for function 'fetestexcept'
	/usr/include/fenv.h:163: error: invalid storage class for function 'fegetround'
	/usr/include/fenv.h:178: error: invalid storage class for function 'fesetround'
	/usr/include/fenv.h:204: error: invalid storage class for function 'fesetenv'
	/usr/include/fenv.h:225: error: invalid storage class for function 'fegetexcept'

>How-To-Repeat:
	Try to compile something including <fenv.h> with gcc41 (or later).

>Fix:
	The following patch, which remove the clause "static", fixes the
	problem for me. It should surely be applied to the other
	achitectures too, but I have only tested it on i386.
