I had a similar problem (probably it is the same) on the NT 4.0 =
platform. Here is what I suggest you to do in order to fix it:
1) Remove evrything related to DJGPP from your system.
2) Unpack/unzip the DJGPP package with a utility that will generate =
files with 8 characters long names and 3 characters long extension.
3) Once this is done, go under ...\DIGPP\LANG\CXX. There, you will find =
a bunch of include files. These files are used by the C++ compiler. It =
will be necessary to edit each of these files and modify the #include =
directives in such a way that every time you will encounter an #include =
directive containing the name of a file that is longuer than 8 =
characters, you will replace it by its 8 characters conter part. To =
illustrate that, let say we have the following #include statement:
#include <streambuf.h>
Once modified, it will look like this:
#include <streambu.h>
It is necessary to do that since the name of the file streambuf.h has =
been truncated in step 2).
If you follow these steps, I am pretty sure you will fix your problem. =
By the way, part of that solution come from DJ Delorie himself...
Good luck,
Pierre Beaulieu

First Problem:=20
When I want to link my C-programs, I get the error message under DOS =
:=20
ld.exe: cannot open -lstdcx: No such file or directory (ENOENT)=20
although I followed the instuctions, listed in the problems.txt. But =
under Windows 95 everthing works fine. What did I do=20
wrong ?=20
Second Problem:=20
Under Borland C++ I could use the Pseudo-Registers to print, =
calculate and manipulate the values of the=20
CPU-Registers. But now I only have the Registers, defined in the =
UNION REGS, that means when I want to print a=20
Register-value which I have manipulated before with the inline =
assembler, the Pseudo-Registers are not updated. They=20
will only be updated when an interrupt is used. So what can I do ? =
Do I really have to copy the value of the Registers in a=20
variable and print the variable instead of the Registers ?=20
Third Problem:=20
In Real-Mode I could move a block of memory by storing the values of =
the Segements in the ES and DS Register, and=20
the Offset in the DI and SI Register. What do I have to do, to move =
a block of memory in the protected-mode (in=20
assembler) ? Do I need to store the selectors in one of these =
Registers ?=20
Do the Djgpp - C++ - Copy - Routines move 4 bytes at one time or =
only 1 or 2 byte(s) ? Can I improve the=20
performance by using the Fat Ds Method when I copy memory-blocks, or =
do this method only make sense when I=20
want to change, read or write the bytes in the memory ? I have to =
know this because of my Vesa-Functions.=20
