Try this:

int main(int argc,char *argv[])
{
int i;
for (i = 0; i < argc; i++)
   printf("\n%s", argv[i]);
return 0;
}

Simple enough.  Well, compile it and execute it with
the single string "..." (no quotes) on the command line.  You should see:

<whatever you named your executable>
.

In other words, where are the other two dots?  I tried the same bit of code with
Mingw32 (GCC 2.95.2) to determine if it was DOS 7 or DJGPP that was doing this.
It wasn't DOS, since the Mingw32 version worked OK...  (Pun intended)  At the time,
I was running under a Win95 (Windows 95. [Version 4.00.950]) DOS shell on a P166.
I first encountered this bug using GCC 2.8.1, and it's still there with 2.95.1.
Anyhow, thanks for making DJGPP; even with small bugs, it is great!

That's not a bug, but a feature. To see what it does, execute
the dest from your c:\ directory, i.e.:

	c:
	cd \
	d:\some\dir\yourtest ...

You'll get a list of all the directories and subdirectories of c:\ .
This is a feature of the support for filename globbing DJGPP offers. 
Sort of a poor man's 'find':

	grep size_t c:/djgpp/include/.../*.h

to search for 'size_t' in all of DJGPP include files

Enclose the ... into quotes "...", and they won't be interpreted as a filename.
