[help-gengetopt] Include getopt code

[T Menezes]

Hi,

This morning I tried to use gengetopt (2.19.1) on a project running in 
Windows. For the first time, I added '--include-getopt' on the command 
line because I wanted to make the project as self-contained as possible 
(some of the people involved with this piece of code do not know and are 
not inclined to learn Linux-based code/libraries).

When I then used the cmdline.h & cmdline.c files in my project, an error 
message popped up saying the compiler (sadly using MS Visual Studio on 
this particular occasion) cannot find getopt.h.

I was under the impression that the '--include-getopt' option would sort 
out all getopt-related issues (particularly useful in systems where the 
getopt library isn't available).

Could anyone please clarify how I should be using the version of getopt 
generated by gengetop?

Many thanks,
TM
