(add_subroutines): Likewise. * intrinsic.h: Prototypes for gfc_check_ctime, gfc_check_ctime_sub, gfc_check_fdate_sub, gfc_resolve_ctime, gfc_resolve_fdate, gfc_resolve_ctime_sub, gfc_resolve_fdate_sub. * gfortran.h: Add GFC_ISYM_CTIME and GFC_ISYM_FDATE. * iresolve.c (gfc_resolve_ctime, gfc_resolve_fdate, gfc_resolve_ctime_sub, gfc_resolve_fdate_sub): New functions. * trans-decl.c (gfc_build_intrinsic_function_decls): Add gfor_fndecl_fdate and gfor_fndecl_ctime. * check.c (gfc_check_ctime, gfc_check_ctime_sub, gfc_check_fdate_sub): New functions. * trans-intrinsic.c (gfc_conv_intrinsic_ctime, gfc_conv_intrinsic_fdate): New functions. (gfc_conv_intrinsic_function): Add cases for GFC_ISYM_CTIME and GFC_ISYM_FDATE. * intrinsic.texi: Documentation for the new CTIME and FDATE intrinsics. * trans.h: Declarations for gfor_fndecl_ctime and gfor_fndecl_fdate. * intrinsics/ctime.c: New file. * configure.ac: Add check for ctime. * Makefile.am: Add ctime.c * configure: Regenerate. * config.h.in: Regenerate. * Makefile.in: Regenerate.
