Installation of lrzsz

Apply a patch to fix various configuration, build, and security issues: 

patch -Np1 -i ../lrzsz-0.12.20-third_party_fixes-1.patch

Remove an unneeded prototype that causes a build failure: 

for i in src/l{r,s}z.c; do
  sed -i '/extern\ char\ \*strstr/d' $i
done

Add and remove some files, then regenerate the autoconf files: 

touch config.rpath &&
rm -vf missing &&
rm -vf acconfig.h &&
autoreconf -fiv -I/usr/share/gettext/m4

Install lrzsz by executing the following commands: 

./configure --prefix=/usr --disable-nls &&
make

Now as the root user: 

make install &&

for x in {r,s}{b,x,z} ; do
    ln -svf l${x} /usr/bin/${x} &&
    ln -svf l${x:0:1}z.1 /usr/share/man/man1/${x}.1 &&
    [ "${x:1:1}" = "z" ] || ln -svf l${x:0:1}z.1 /usr/share/man/man1/l${x}.1
done

Command Explanations

touch config.rpath: This command creates an empty file that automake wishes to use, but is missing from the distribution.

rm -vf missing: This command deletes the missing file as it is too old to be used. automake, when executing autoreconf, will regenerate this file that will be current.

rm -vf acconfig.h: autoheader does not like the acconfig.h file existing, so this command deletes it.

--disable-nls: This parameter disables NLS support as it is broken for this package due to missing files.

for i in {r,s}{b,x,z} ; do...: This command block creates compatibility symlinks for the original rzsz package, which is required for minicom-2.11.1.
