---------------------------------------------------------------------- (0005383) Vincent Lefevre (reporter) - 2021-06-16 22:19 https://austingroupbugs.net/view.php?id=713#c5383 ---------------------------------------------------------------------- But there is an issue concerning the implementations. If POSIX specifies more than ISO C, this means that C compilers used for the c99 utility would need to have a POSIX C dialect mode. Under Debian at least, c99 is a script that runs the gcc command, but GCC doesn't currently have a POSIX mode: if some code has undefined behavior in ISO C and GCC can detect this, it may consider it as dead code (or deduce some value ranges for variables), yielding incorrect code generation for POSIX C source that assumes unspecified results.
