| Portability problems not fixed by Gnulib: |

| This function is missing on some platforms: |
| mingw, MSVC 14. |
| @item |
| On some platforms, @code{fork} followed by a call of the @code{exec} family |
| (@code{execl}, @code{execlp}, @code{execle}, @code{execv}, @code{execvp}, |
| or @code{execve}) is less efficient than @code{vfork} followed by the same |
| call. @code{vfork} is a variant of @code{fork} that has been introduced to |
| optimize the @code{fork}/@code{exec} pattern. |
| @item |
| On Windows platforms (excluding Cygwin), this function is not implemented; use |
| @code{spawnvp} instead. |
