widl [6/7]: Don't compare result of read() to unsigned type.

[Dan Hipschman]

This eliminates a warning about comparing signed and unsigned types.  There's
good reason for this warning, because if read() returns -1 it will be
converted to an unsigned type and the test will fail as if no error had
occurred.

ChangeLog:
* Don't compare size_t to int.
