GCC - shouldn't a warning be issued when assigning an int to a char?

Question

I\'ve recently set up a MinGW + MSYS environment on my laptop to check how things are with Netbeans C/C++ support. Everything seems to work fine, however, during my testing

Answer 1

You're looking for

-Wconversion

You'd have to ask a gcc developer for the specific reasons why some warnings aren't included in -Wall or -Wextra.

Anyway, these are the flags I use:

-Wall -Wextra -Wmissing-prototypes -Wmissing-declarations -Wshadow
-Wpointer-arith -Wcast-align -Wwrite-strings -Wredundant-decls -Wnested-externs
-Winline -Wno-long-long -Wconversion -Wstrict-prototypes

As other's have pointed out, the behaviour of -Wconversion changed with version 4.3 - the old warning about prototypes forcing a type conversion is now available as -Wtraditional-conversion.
