Hi,

I've just installed DJGPP 2.0 (DOS) (gcc,gpp,c and c++ libs, etc... i'm quite 
sure that nothing is missing).

I wanted to translate one of my C++ DOS (real mode) program to DJGPP that use 
findfirst/findnext; it compiled OK, but when it calls findfirst/findnext, names 
of files it find (pointed by ffblk.ff_name) don't have their first two chars !

So I've made a little program that only make a 'dir *.*' with those functions :
Compiled as a C source file (.c), the exe works (correct filenames);
Compiled as a C++ source file (.cc), the first 2 characters of each filename 
are missing !

In dir.h (C and C++ compatible), ffblk structure size is 290 (manually 
counted).
A sizeof(ffblk) gives me 290 under C, and 292 under C++ (here are my 2 bytes :)

Here is what I think : if C and C++ libraries (.a) that implement 
findfirst/findnext are different, i suppose that the C++ one have been compiled 
with a different header (dir.h) than the one i have.
But if there is only one library implementing ff/fn...i don't know !

Then, what must i do ? Please don't answer that i should use _dos_findfirst 
(maybe it won't work better, and i want to have an "easily portable" source), 
or command line gobbling (works only at starting time !), or that ff_name-2 is 
where i will find my correct filenames under C++ (true but...)

P.S.: (Maybe here is the problem, see '==>')
Installed packages are (binaries) djdev200, bnu252, gcc272, gpp272,==> lgp271 
(C++ libraries ! 272 available ?), mak373, and a few other ones (info, dpmi, 
misc)...
My configuration is P120 with Windows 95 and Dos 6.2.
