Hi, everyone. I'm building a project in C. My idea is that I want it
to be mostly C89, except that I will be using certain features of C99.
What compiler flags do I need to tell GCC what I want?
At present, if I compile with -std=c99, I get no errors or warnings at
all. If I compile with -std=c89, I get the following warnings:
(When I use macros with ... and __VA_ARGS__)
warning: anonymous variadic macros were introduced in C99
(When I use long string literals)
warning: string length '613' is greater than the length '509' ISO C90
compilers are required to support
(When I use vsnprintf)
warning: implicit declaration of function 'vsnprintf'
(When I initialize a struct with run-time data)
warning: initializer element is not computable at load time
