pic12f675.h as currently distributed does not contain any #pragma
lines. Are you sure you actually use your newly built sdcc ('which
sdcc' might tell you that you actually use /usr/local/bin/sdcc instead
of /home/login/bin/sdcc or wherever you installed your built sdcc). I
guess that Fedora comes with some ancient (?) sdcc installed via the
package manager, which now causes confusion.
Please ./configure --prefix=$HOME/local sdcc, make && make install it,
export PATH=$HOME/local/bin:$PATH, purge the shell's cache using 'hash
-r' and try again. You might also pass
-I/path/to/non-free/include/pic14 to force the compiler to look there
first.
The other errors seem to be follow-ups.

Ah, interesting. So there is / was an sdcc installed via yum. Please
uninstall and try again.

The PIC backends are usually useable, though they are not as mature as
most other backends.
