Preprocessed source for tftopl.c

Hello!

I just noticed that we run into a new regression which seems to have been
introduced with gcc-5.

The compiler output is as follows:

gcc -DHAVE_CONFIG_H -I. -I../../../texk/web2c -I./w2c 
-I/«PKGBUILDDIR»/Work/texk -I/«PKGBUILDDIR»/texk  -Wimplicit -Wreturn-type -g
-O2 -c -o tftopl.o tftopl.c
tftopl.c: In function 'mainbody':

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccRGajx7.out file, please attach this to
your bugreport.

A full build log can be found in [1]. The build log of a previous, successful
build with gcc-4.9 can be found in [2]. I am attaching the preprocessed source
which is mentioned in the build log.
