Some functions in math.h (like rint), are inlined in the math.h
header, but fail to compile with an error when used:
<output>
[EMAIL PROTECTED]:~/prjs/wince/cegcc/test/math_h_header$ cat main.c
#include <math.h>
int main( void )
{
double i = rint( 3.14 );
return 0;
}
[EMAIL PROTECTED]:~/prjs/wince/cegcc/test/math_h_header$
arm-wince-mingw32ce-gcc main.c
main.c: In function 'main':

</output>
The following patch tries to fix this:
