Make hdf5-1.14.0 on Debian: conflicting types for ‘ssize_t’

I have tried building HDF5 from source, on a virtual machine Linux #1 SMP Debian 5.10.140-1 (2022-09-02). I followed the basic instructions:

         gunzip < hdf5-1.14.0.tar.gz | tar xf -
         cd hdf5-1.14.0
         ./configure --prefix=/usr/local/hdf5 
         make
         make check                # run test suite.
         make install
         make check-install        # verify installation

The configure step runs successfully (after removing the unwanted newline characters \r in the files which caused errors, as explained in 1) but the make command returns the following errors:

HDF5 defines several POSIX things for platforms like Windows, including ssize_t. If it is getting re-defined on Linux, it's probably because the header is being mis-parsed.

Why are you getting Windows line endings on Linux? Where are you getting the source tarball?
