        "All variables and functions, which are decalred as yy_size_t in the flex-2.6.0-generated code, are of type int in the flex-2.6.4-generated code. No variable or function is declared as the type yy_size_t in the code generated by flex 2.6.4. Therefore, the definitions of variables and functions which were generated by flex (2.6.4) and which should be of type yy_size_t conflict with the hard-coded definitions copied from ncap_lex.l.
        The error is only thrown in combination with --enable-optimize-custom or --enable-debug-custom because only then the conflicting hard-coded definitions are considered by the compiler/preprocessor (#if ... && (defined(ENABLE_DEBUG_CUSTOM) || defined(ENABLE_OPTIMIZE_CUSTOM)) ...)." 
     Once all platforms upgrade to Flex >= 2.6.4 we can deprecate yy_size_t code
     However, MacOSX may never upgrade to newer Flex
     CZ's decision is to keep current behavior until breakage cannot be ignored and then sacrifice buildability on older Flex */

     Not including sign signifiers [+-]? causes bug parsing --mask_condition expressions with negative msk_val
     Without the optional signage, ncap_ncwa_scn() ignores unary negative sign so msk_val is returned as abs(msk_val)
     Prepending [+-]? to number rules for doubles, floats etc fixes this particular problem but causes others
     Specifically, when lexer ingests signage tokens then parser treatment of subtraction fails, e.g.,
     ncap -O -D 4 -v -s 'zero=1-1.0' ~/nco/data/in.nc ~/foo.nc # Result is zero=1
