If you have unzipped DJGPP with WinZip or some other program which 
supports long file names on NT, then that is your problem.  Remove 
everything you installed and re-unzip DJGPP zip files with a DOS program 
like PKUNZIP 2.04.  Then everything will work.

Explanation: DJGPP doesn't have access to long file names on NT, so it 
needs to see streambu.h.  But when you unzip the distribution with 
WinZip, NT creates 8+3 aliases for long file names which include those 
pesky ~1 numeric tails, so what you get is stream~1.h, which is not the 
same.

An alternative solution is to turn off the numeric tails.  The DJGPP FAQ 
list explains in section 8.2 how to do that.  But you will have to 
install DJGPP from scratch after turning off numeric tails anyway, since 
it only has effect on files created *after* turning it off.

There's a DJGPP clone of the man command, in v2apps/man12b.zip.  But I 
don't think it will help you in this matter, since none of the DJGPP 
documents are in man page format.  Maybe you need the info reader, in 
which case get and install v2gnu/txi312b.zip.

Please do NOT edit DJGPP.ENV!  Its syntax is cryptic, and without a full 
understanding of what you are doing, you will break a lot of things in a 
way which will drive you crazy!  DJGPP.ENV is instrumental in making 
everything work in a seamless matter, requiring you to set a single 
environment variable.  Don't mess with it.

I suggest to revert to the version of DJGPP.ENV that came with 
djdev201.zip.  Anything you need to set in the environment, set either in 
AUTOEXEC.BAT or in the registry.  (Actually, you only need to set the 
DJGPP environment variable and add the DJGPP bin subdirectory to your 
PATH.)

It does work for everybody else.  You have just installed it incorrectly.
