POSIX requires fexecve, and we had all the pieces ready to go. And to my
surprise, we've had execvpe in the sources for a long time, but just
failed to export it (glibc just added execvpe in 2.10). OK to apply,
along with the corresponding patch to new-features.sgml and tweaking
unistd.h in newlib?
P.S Any reason that "dtable.h" and "cygheap.h" aren't self-contained?
2009-09-26 Eric Blake
* exec.cc (fexecve): New function.
* cygwin.din (execvpe, fexecve): Export new fexecve and existing
execvpe.
* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump.
* posix.sgml: Mention them.

Don't work too hard, make some time for fun as well!
