+Problems with MS Visual C++ Version 7 / VC.NET
+----------------------------------------------
+Beside licensing problems with these compilers, there are known problems with DLL's.
+If Ethereal is compiled with MSVC Version 7, there are conflicts in the MSVCRT DLL's,
+The MSVCRT.DLL includes the standard ANSI-C functions like fopen, malloc, etc.. MSVCRT.DLL
+is shipped with the MSVC 6 compiler versions, and dynamically linked to prebuild DLL's like
+the one's for gtk, glib and such. The MSVC 7 compiler now uses and ships MSVCRT71.DLL with
+it, which is incompatible with MSVCRT.DLL. So when using the MSVC 7 compiler, some parts of
+the Ethereal code uses MSVCRT71.DLL, and some others (indirectly from e.g. the gtk DLL) will
+use MSVCRT.DLL. This will result in incorrect file handles and such.
+
+The same problem seems to apply on all MSVC compilers after version 6, like the
+"Microsoft Visual C++ Toolkit 2003".
