Bug in Gnu C compiler version 1.26: type checking in prototypes

Compiling the following code with gcc version 1.26 gives incorrect error
messages.  Type checking in prototypes is not done correctly.  It looks
like gcc converts the type given in the prototype to int (or whatever
the argument type is usually converted to in function arguments).
This converted type is then compared against the actual function
arguments in the function definition.  The error is reported in the
function definition.  The fix must prevent converting argument types
in prototypes.

The program generates the error when compiled with the command
  gcc -c foo.c

The computer is a 386-based AT with 10MB of ram and a 350MB scsi disk.
It is running Microport System V/386 (System V release 3.0).
