>Description:
Various identifiers defined by the arm32 softfloat package used in
libc and defined with external linkage occupy application name space,
which may yield the obvious clashes.
>How-To-Repeat:
Run a piece of code like this, and watch it die.
#include <stdlib.h>
void float64_le(void);
int main(int, char *[]);
void float64_le()
{
abort();
}
int
main(int argc, char *argv[])
{
double a = 1.0, b = 2.0;
return (a <= b);
}
>Fix:
Remove external linkage where not required; move other identifier
names into implementation name space (suggestion: add a `_arm32_'
prefix).
