The tests: - 26_numerics/c99_classification_macros_c++.cc - 26_numerics/c99_classification_macros_c.cc fail because C99 and C++ disagree over fpclassify() The following patch to /usr/include/math.h does the job, but I haven't checked it against the standards. I don't have a newlib tree at present, so I am unsure which source file needs the patch. Tested by successful compilation of above tests. 2003-07-05 David Billinghurst * math.h: Do not define ISO C99 types and macros for C++ --- math.h.orig 2003-07-05 09:10:07.000000000 +1000 +++ math.h 2003-07-05 09:23:25.000000000 +1000 @@ -63,9 +63,8 @@ #endif /* ! defined (__math_68881) */ #endif /* ! defined (_REENT_ONLY) */ -#ifndef __STRICT_ANSI__ - /* ISO C99 types and macros. */ +#if ! defined (__STRICT_ANSI__) && ! defined (__cplusplus) #ifndef FLT_EVAL_METHOD #define FLT_EVAL_METHOD 0 @@ -116,8 +115,10 @@ (__extension__ ({__typeof__(x) __x = (x); __typeof__(y) __y = (y); \ fpclassify(__x) == FP_NAN || fpclassify(__y) == FP_NAN;})) -/* Non ANSI double precision functions. */ +#endif /* ! defined (__STRICT_ANSI__) && ! defined (__cplusplus) */ +/* Non ANSI double precision functions. */ +#ifndef __STRICT_ANSI__ extern double infinity _PARAMS((void)); extern double nan _PARAMS((void)); extern int isnan _PARAMS((double)); -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
