- Subject: Defining a HAVE_J0 in config.h for gfortran?
I'm contemplating adding j0, j0f, j1, j1f, y0, y0f, y1, and y1f
intrinsic functions to gfortran for compatibility with g77. In
gcc/libgfortran I can modify configure.ac with a line similar to
AC_CHECK_LIB([m],[j0],[AC_DEFINE([HAVE_J0],[1],[libm includes j0])])
to check that j0 is present in libm. I however need the HAVE_J0
symbol in gcc/gcc/fortran. There is no configure.ac in this
directory, so I need some other way to define HAVE_J0. Any pointers
would be appreciate.
