Third-party libraries made for C Version 4.00 can be used with C
Versions 5.00 and C 5.10. An attempt was made to make third-party
libraries as compatible as possible. However, a few functions were
changed to conform to the ANSI C draft and may cause problems.
Functions such as rename() and memcpy() had their arguments reversed
from the C 4.00 to C 5.00 libraries; thus, calls to these functions
from C 4.00 libraries do not work properly. This also applies when
using third-party libraries with QuickC 1.x and QuickC 2.00.

To use libraries made for C 4.00 under C 5.00 or above, you must link
with /NOD and specify the C 5.00 combined library to use, as follows
(the /NOD tells the linker not to use the default libraries for C 4.00):

   LINK /NOD file.c ,,, oldlib slibce.lib

In QuickC, this can be done as follows by setting the environment
variable LINK to /NOD and specifying the QuickC combined library to
use in a program list:

   set LINK=/NOD

If there are still linker errors, you must request library updates
from the third-party vendor.
