The causes a problem with one of our older hosts. On the old hosts, getline prototype is protected by #ifdef __USE_GNU This should be OK if the C file has #define _GNU_SOURCE. However, because of your patch, the stdio.h is included before _GNU_SOURCE is defined. The result is warnings like this aisimage.c: In function ?aisimage_generate?: aisimage.c:313: warning: implicit declaration of function ?getline? kwbimage.c: In function ?kwdimage_set_ext_header?: kwbimage.c:236: warning: implicit declaration of function ?getline? imximage.c: In function ?parse_cfg_file?: imximage.c:430: warning: implicit declaration of function ?getline? pblimage.c: In function ?pbl_parser?: pblimage.c:137: warning: implicit declaration of function ?getline? ublimage.c: In function ?parse_cfg_file?: ublimage.c:179: warning: implicit declaration of function ?getline?
