execv (GNU Gnulib)

Gnulib module: execv

Portability problems fixed by Gnulib:

On Windows platforms (excluding Cygwin), this function does not pass command-line arguments correctly if they contain space, tab, backslash, or double-quote characters.
On Windows platforms (excluding Cygwin), this function spawns an asynchronous child process and then exits the current process immediately. As a consequence, the parent of the current process 1. may incorrectly proceed as if its child had exited, and 2. will never see the child’s exit status.
On Windows platforms (excluding Cygwin), the return type of this function is intptr_t, not int.

Note: The Gnulib replacement for this function is not async-safe, that is, it must not be invoked from a signal handler.

Portability problems not fixed by Gnulib:

On some platforms, a script without executable permission is still run: Cygwin 1.5.x.
