tig uses a char as a flag, and expects that to have three values: TRUE, FALSE, and -1. When char is unsigned char (such as on PPC), this fails with the compiler warning "comparison is always false due to limited range of data type".
So explicitly make the flag a signed char.
Detecting the int8_t type with the autoconf macro AC_CREATE_STDINT_H would probably be a better fix.
