All this problems are not fatal. There is plenty of the "X" to C
translators, even C++. Most interesting for me is Vala. And generated
by Vala C code looks nice. Your point of view is a point of the
translator writer. From the user point having a C generated code drops
all needs to descripe how this or thats is implemented by translator,
a more portable code because a C compilers are written for everything
(8051 for example), chance quickly replace and compare different C
compilers and interpreters as backends, chance to use different C
tools  to transform and analyze a code, etc....

PS: you just say that C is not suitable for the system programming
