        * libc/stdlib/mprec.c (ulp, b2d, d2b): changed a few expressions
        like  x << y-z  to the equivalent  x << (y-z).
        (d2b): changed if statements with assignment to perform the
        assignment prior to the if check.
        * libc/reent/reent.c: included stdlib.h for "_free_r" prototype.
        * libc/unix/getpass.c (getpass): moved "echo" assignment out of if.
        * libc/unix/ttyname.c: included string.h for "strcpy" prototype.
        * libc/unix/getcwd.c (ISDOT): added parentheses to clarify && and ||
        precedence.
        * libc/include/sys/unistd.h: added "vfork" prototype (for popen.c).
        Added "_execve" prototype (for execl.c, execle.c, execv.c, and
        execve.c).
        * libc/posix/popen.c (popen): added parentheses to clarify && and ||
        precedence.
        * libm/math/e_cosh.c (__ieee754_cosh): changed parentheses to
        clarify && and || precendence (and to remove pascalism).
        * libm/math/e_sinh.c (__ieee754_sinh): Ditto.
        * libm/math/s_infconst.c: added another pair of braces to all
        initializers for __infinity (need three: for __infinity[1] array,
        for union __dmath, and for i[2]).
