[Dev-C++] Unable to compile

[<Luc...@wa...>]

I installed Dev-C++ 4.9.8.10 on a new computer, then copied in a
directory on that PC my project with all source files (10 000 lines) and
the .dev file.
            This project compiles OK on the old PC with Dev-C++
4.9.8.10, but on the new I can only get the message =93unable to run
program file=94 on Line 2 (whatever the file it is). I tried Rebuilding
all source files, or compiling file by file, but get only this message,
immediately after starting the compile. The only created files are
Project1_private.h and Projet1_private.rc. No .o or .exe are created.
            I tried uninstalling and reinstalling Dev-C++, with no
success. So I can edit the files, but can=92t compile anything.

In the =93Compile Log=94 window of Dev-C++:
Compiler: Default compiler
Building Makefile: "F:\Project\Makefile.win"
