+Subject: [PATCH] ht: fix build failure on -funsigned-char platforms
+
+powerpc (and arm) have 'char' == 'unsigned char' by default.
+This causes build failures on c++11:
+
+```
+$ ./configure CFLAGS=-funsigned-char CXXFLAGS=-funsigned-char
+$ make
+
+g++ -DHAVE_CONFIG_H -I.   -I./analyser -I./asm -I./info -I./io/posix -I./io -I./output -I./eval -I.   -DNOMACROS -pipe -O3 -fomit-frame-pointer -Wall -fsigned-char -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64  -std=c++14 -Woverloaded-virtual -Wnon-virtual-dtor -funsigned-char -MT htcoffhd.o -MD -MP -MF .deps/htcoffhd.Tpo -c -o htcoffhd.o htcoffhd.cc
+htcoffhd.cc:93:1: error: narrowing conversion of '-1' from 'int' to 'char' inside { } [-Wnarrowing]
+ };
+ ^
+htcoffhd.cc:131:1: error: narrowing conversion of '-1' from 'int' to 'char' inside { } [-Wnarrowing]
+ };
+```
+
+Use 'signed char' explicitly to maintain existing behavior.
