Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: mingw.

  * On some platforms, fork followed by a call of the exec family (execl, execlp, execle, execv, execvp, or execve) is less efficient than vfork followed by the same call.  vfork is a variant of fork that has been introduced to optimize the fork/exec pattern.

  * On Windows platforms (excluding Cygwin), this function is not implemented; use spawnvp instead.
