• obsoleted Renamed to VL_PROG_CC_WARNINGS, or use AX_CFLAGS_WARN_ALL.

Enables a reasonable set of warnings for the C compiler. Optionally, if the first argument is nonempty, turns on flags which enforce and/or enable proper ANSI C if such are known with the compiler used.

Currently this macro knows about GCC, Solaris C compiler, Digital Unix C compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C compiler.
