[tlbuild] autosp.c compile fixes with -Werror...

[Norbert Preining]

Hi

it seems that autosp.c needs a bit of fix up. Compiling with all kind of
warnings as errors turned on I needed to apply the following fix:
--- texlive-bin-2018.20180312.46927.orig/utils/autosp/autosp-src/autosp.c
+++ texlive-bin-2018.20180312.46927/utils/autosp/autosp-src/autosp.c

     lineno++;
     process_line ();
     c = getc (infile);

The fgets one is for a warning that the return value of fgets is not
used.

What should we do with these kind of things?

Best
