Yes and no. The Fortran 2008 draft has the following functions, but they are
not necessarily called the same as the typical vendor extensions.
http://j3-fortran.org/doc/year/07/07-007r2.pdf

ACOSH, ASINH, ATANH Inverse hyperbolic functions  [exist in gfortran]
BESSEL_J0, _J1, _JN, _Y0, _Y1, _YN  Bessel functions [exist as BESJ0 etc.]
ERF   Error function [exists]
ERFC  Complementary error function [exists]
ERFC_SCALED Exponentially scaled ERFC [not in gfortran]
GAMMA Gamma function [not in gfortran ;-)]
HYPOT = sqrt(x**2+y**2) [not in gfortran]
LOG_GAMMA [not in gfortran ;-)]
NORM2  L_2 norm [not in gfortran]

No specific names seems to exist for those whereas the compiler extensions
have:
for GAMMA: DGAMMA and for LGAMMA [F2003: LOG_GAMMA]: ALGAMA, DLGAMA.
