Should / must we do anything about the issue? At least Python builds with a C89 compiler except of ssl and socket module. Those modules include non C89 compliant header files from the OS (bluetooth and tpic). $ LC_ALL="C" CC="gcc -std=c89" make gcc -std=c89 -pthread -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o Objects/object.o Objects/object.c Objects/object.c: In function 'internal_print': Objects/object.c:295: warning: ignoring return value of 'fwrite', declared with attribute warn_unused_result Objects/object.c:304: warning: ignoring return value of 'fwrite', declared with attribute warn_unused_result gcc -std=c89 -pthread -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o Python/marshal.o Python/marshal.c Python/marshal.c: In function 'w_string': Python/marshal.c:90: warning: ignoring return value of 'fwrite', declared with attribute warn_unused_result gcc -std=c89 -pthread -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o Modules/main.o Modules/main.c Modules/main.c: In function 'usage': Modules/main.c:134: warning: format not a string literal and no format arguments Modules/main.c:135: warning: format not a string literal and no format arguments Modules/main.c:136: warning: format not a string literal and no format arguments

What operating system is this on? In any case, the warnings look harmless.

These are probably all fixed by now.
