>Description:
cc(1) can't compile a file using <math.h> only.
>How-To-Repeat:
o Sample file, sample.c:
#include <math.h>
double
a(n)
double n;
{
return sqrt(n);
}
o Compile result:
% cc -traditional -fno-builtin -c sample.c
taca@edge[65]:cc -traditional -fno-builtin -c sample.c

In file included from sample.c:1:
/usr/include/math.h:27: syntax error before `char'
/usr/include/machine/math.h:8: warning: array `__nanf' assumed to have one element
/usr/include/math.h:27: warning: array `__infinity' assumed to have one element
>Fix:
Include <sys/cdefs.h> somewhere in <math.h> with checking
definition of _SYS_CDEFS_H_.
The same problem may exist in other header files.
