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

Hi Bob,

The changes are not necessary, but on Debian we automatically compile
with warnings turned to error. Here we are using gcc-7 at the moment and
gcc-8 is in preparation I guess.

The format string warning has been around since quite some time in Gcc,
and I have fixed most occurrences in web2c code. The point is to make
sure that if you don't have a format string then the string you want to
print could contain % directives which then are being tried to be
satisfied by printf etc etc.

The other was new to me, but well, error handling.

All the best

Norbert
