strfromd.3: restrict? C99?

["Alejandro Colomar (man-pages)" <alx.manpages@gmail.com>]

Hello Michael, Wainer,

It's weird.  The only manual page that I've seen using restrict, and I 
think it's wrong.  glibc doesn't use it:

.../glibc$ grep_glibc_prototype strfromd
src/gnu/glibc/stdlib/stdlib.h:212:
extern int strfromd (char *__dest, size_t __size, const char *__format,
		     double __f)
      __THROW __nonnull ((3));
.../glibc$ grep_glibc_prototype strfromf
src/gnu/glibc/stdlib/stdlib.h:216:
extern int strfromf (char *__dest, size_t __size, const char *__format,
		     float __f)
      __THROW __nonnull ((3));
.../glibc$ grep_glibc_prototype strfroml
src/gnu/glibc/stdlib/stdlib.h:220:
extern int strfroml (char *__dest, size_t __size, const char *__format,
		     long double __f)
      __THROW __nonnull ((3));
.../glibc$

And the manual page states that it conforms to some standards, but I 
haven't found it in C99 (neither in C11 nor C18) nor in POSIX:

$ man 3 strfromd | sed -n '/CONFORMING/,/^$/p'
CONFORMING TO
        C99, ISO/IEC TS 18661-1.

$ man 3p strfromd
No manual entry for strfromd in section 3p
$

I don't know what that other "ISO/IEC TS 18661-1" is.

Should I remove restrict?  And C99 from the CONFORMING TO section?

Thanks,

Alex
