Since f2ed27cf5f (between 4.89 & 4.90) we've documented
a requirement on C99-capable compilers. This was the
introduction of specified-initialiser use in the Exim code.
How do people feel about other more-modern C features?
This was triggered by the Postgres hackers ML pointing out
that C99 permits variable declaration embedded in "for"
statements, eg:
for (int i = 0; ...) { ... }
Ref:
6.8.5 Iteration statements
Syntax
iteration-statement:
while ( expression ) statement
do statement while ( expression ) ;
for ( expr-opt ; expr-opt ; expr-opt ) statement
for ( declaration ; expr-opt ; expr-opt ) statement
I'm tempted by that one.
I severely dislike C++ - style one-line comments: code // comment.
I don't like mixing declarations with code.
Other possibilities mentioned include:
- variadic macros
- compound declarations: function((struct x) {1, 2})
Comments?
