$! customize CFLAGS for version of VMS, CRTL, and C compiler.
$!-----------------------------------------------------------------
$!  these defines work for OpenVMS Alpha v6.2 and DEC C v5.3

$! For  VMS 4.7 and VAX C v2.4  
$! ("Compiler abort - virtual memory limits exceeded" if attempt
$!  to include all applicable terminals, but otherwise builds OK.  
$!  Runtime problem: an exit handler error, also w/ gcc build;
$!  a VAXCRTL atexit bug?)
$!
$! Note: VAX uses  D_FLOAT, maximum exponent ca 10e +/- 38;
$!       will cause problems with some of the demos
$!
$!$ CFLAGS    = "/NOOP/DEFINE=(NO_STRSTR, NO_SYS_TYPES_H, "-

$!$!
$!
$!-----------------------------------------------------------------
$!
$! This will build with gcc v1.42 on VMS 4.7
$! (no virtual memory limit problem)
$!
$! gcc v1.42 string.h can prefix str routines w/ gnu_ (ifdef GCC_STRINGS)
$! but the routines in GCCLIB are not prefixed w/ gcc_  :-(
$! link with GCCLIB, then ignore the link warnings about multiple
$! definitions of STR... in C$STRINGS
$!
$! GCC v1.42 has a locale.h, but neither gcc nor VMS v4.7 VAXCRTL has 
$! the  setlocale function
$!           
$!
$! Note: _assert.c defines assert_gcc, if ndef NDEBUG, but
$!        cgm.trm undefines NDEBUG, so we always compile/link  _assert.c
