| Subject: | C plugin: Integers incorrectly detected, 0/4 ignored, typedef ignored |
The attached script shows Syntax::Highlight::Engine::Kate::C failing to
detect the integers 0 and 4.
Other positive integers are detected as 'float'. Negative integers are
correctly detected as 'decval'.
'typedef' is also ignored completely.
ANSI_C89 mode also shows the same problem.
