this indeed seems like a bug. with lfn disabled in djgpp.env (+lfn=n),
the following program:

#include <stdio.h>

int main(int argc, char *argv[])
{
 int i;
 for(i=0; i<argc; i++)
  puts(argv[i]);

 return;
}
produced:
D:\djgpp\C\TEST> testlfn *.c
d:/djgpp/c/test/testlfn.exe
bernoulli.c
simpldtst.c
simplw.c
testlfn.c
tt.c

then i did (with lfn still disabled in djgpp.env)
D:\djgpp\C\TEST> set lfn=n

D:\djgpp\C\TEST> testlfn *.c
d:/djgpp/c/test/testlfn.exe
bernou~1.c
simpld~1.c
simplw.c
testlfn.c
tt.c

incidentally, with set lfn=n, +lfn=y, you still get the short names.

it seems like a bug in the startup code.

(by the way, if i run the following code with +lfn=n set in djgpp.env
but not in the environment, i do get lfn=n output:

#include <stdio.h>
int main(int argc, char *argv[], char* envp[])
{
 int i;
 for(i=0; envp[i] != NULL; i++)
  puts(envp[i]);
 for(i=0; i<argc; i++)
  puts(argv[i]);
 return;
}
)
