When running the batch file STARTUP.BAT that comes with Microsoft C
versions 6.00 and 6.00a, it is possible to receive the following
error:

    U1073: don't know how to make 'stdio.h'.

This can be caused by having more than one search path for the INCLUDE
environment variable, as shown in the following example:

   include=c:\c600\include;c:\masm\include

To correct the problem, only one search path should be used, as in the
following example:

   include=c:\c600\include

Microsoft has confirmed this to be a problem in the C Compiler
versions 6.00 and 6.00a. We are researching this problem and will post
new information here as it becomes available.
