$ make
gcc -c  -I../../../../src/include  -O1 -Wall -Wmissing-prototypes -Wmissing-declarations -g -o like.o like.c
like.c:143: warning: no previous prototype for `inamelike'
like.c:155: warning: no previous prototype for `inamenlike'
like.c:167: warning: no previous prototype for `inamelike_escape'
like.c:180: warning: no previous prototype for `inamenlike_escape'
like.c:193: warning: no previous prototype for `itextlike'
like.c:205: warning: no previous prototype for `itextnlike'
like.c:217: warning: no previous prototype for `itextlike_escape'
like.c:230: warning: no previous prototype for `itextnlike_escape'
like.c: In function `MatchTextLower':
like.c:401: warning: implicit declaration of function `tolower'
