Although an effort has been made to warn about all such cases, there are probably some cases that are not warned about, even though G++ is generating incompatible code.

And fortunately, there was a very easy way to set up a new syntax highlighting in VIM. As always, warnings are not definite indications of errors. When ISO C99 is fully implemented in GCC , this will become the default. So you'd end up with an empty output file, with no idea what went wrong. Gcc Warnings
In normal operation mode, the compiler first parses the program and determines if there are any syntax errors. The most obvious example is an OS kernel. How to draw a path with coordinates defined by f(x) Meaning of "oh freak" Why is water evaporated from the ocean not salty? The option -fno-gnu89-inline explicitly tells GCC to use the C99 semantics for "inline" when in C99 or gnu99 mode (i.e., it specifies the default behavior).
The default is that such warnings are not generated. -c Gcc Flag It looks like this: Undefined first referenced symbol in file main /usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/crt1.o ld: fatal: Symbol referencing errors.

This switch activates warnings for a with of an internal GNAT implementation unit, defined as any unit from the Ada, Interfaces, GNAT, ^^DEC,^ or System hierarchies that is not documented in
The compiler has identified that there may be a problem, but it can produce object code anyway.
