Hi,

I seem to have found a bug but could someone please confirm that it does 
the same on their version. I am using Borland C++ Builder 6 Personal.

Basically I have had this bug for years but was unable to work out what 
it was but now I know.

If you include a file that is not found, but the first 8 characters 
match an existing file then that file is automatically used instead 
which previously caused enormous headcaches wondering why the compiler 
was opening a file that I hadn't requested.

Example.

#include "123456789.h"

if the file is found, it will use it.......... if it is not found but 
the filename "12345678.h" was found in the directory it will open that 
one instead without displaying any sort of an error.

Strangely enough the file found on the hard disk must match the first 8 
characters, not first 7 or any other number. If the #include file is 
less than 8 characters then it will display an error indicating it could 
not find the file
so that could come down to how borland C++ Builder 6 compiler is 
handling filenames.

I have updated to the latest Update 4 to make sure it hasn't been fixed 
already.

Could an update be released for Borland C++ Builder 6 Personal Edition 
please fixing the problem.

Attached are 2 files which when compiled will highlight the problem.

Thanks

Andrew
