/*******
Modifications:
Oct 1997: Changed symbol name extname to appendus (PDW/HSTX)
(Conflicted with a common variable name in FTOOLS)
Nov 1997: If g77Fortran defined, also define f2cFortran (PDW/HSTX)
Feb 1998: Let VMS see the NUM_ELEMS code. Lets programs treat
single strings as vectors with single elements
Nov 1999: If macintoxh defined, also define f2cfortran (for Mac OS-X)
Apr 2000: If WIN32 defined, also define PowerStationFortran and
VISUAL_CPLUSPLUS (Visual C++)
Jun 2000: If __GNUC__ and linux defined, also define f2cFortran
(linux/gcc environment detection)
Apr 2002: If __CYGWIN__ is defined, also define f2cFortran
Nov 2002: If __APPLE__ defined, also define f2cfortran (for Mac OS-X)
Nov 2003: If __INTEL_COMPILER or INTEL_COMPILER defined, also define
f2cFortran (KMCCARTY)
Dec 2005: If f2cFortran is defined, enforce REAL functions in FORTRAN
returning "double" in C. This was one of the items on
Burkhard's TODO list. (KMCCARTY)
Dec 2005: Modifications to support 8-byte integers. (MR)
USE AT YOUR OWN RISK!
Feb 2006 Added logic to typedef the symbol 'LONGLONG' to an appropriate
intrinsic 8-byte integer datatype (WDP)
Apr 2006: Modifications to support gfortran (and g77 with -fno-f2c flag)
since by default it returns "float" for FORTRAN REAL function.
(KMCCARTY)
May 2008: Revert commenting out of "extern" in COMMON_BLOCK_DEF macro.
Add braces around do-nothing ";" in 3 empty while blocks to
get rid of compiler warnings. Thanks to ROOT developers
Jacek Holeczek and Rene Brun for these suggestions. (KMCCARTY)
Dec 2008 Added typedef for LONGLONG to support Borland compiler (WDP)
Jan 2020 Added __attribute__((unused)) for GCC to prevent warnings (C. Markwardt)
Jan 2022 Changed H_CF_SPECIAL definition from 'unsigned' to 'size_t'.
This determines the type of the hidden length argument which
gets added to functions passing strings from Fortran to C.
This change was first required when testing Homebrew
compilers native to Mac/ARM Silicon. (C. Gordon)
Apr 2022 Made equivalent 'unsigned'/'size_t' change to STRING_cfKK(B)
definition. This is required for passing strings from
C to Fortran. To avoid duplication, defined an 'if' block
for setting new CF_STRLENTYPE variable. H_CF_SPECIAL and
STRING_cfKK(B) are now set to this.
May 2022 Set ALL Mac/ARM platforms to 'size_t' for CF_STRLENTYPE
since Clang/Clang++ will not pass GNUC>7 test, yet its
(3rd-party) Fortran still needs this.
