Many compilers have over time added most C99 features (things like //
comments are pretty much universal), but the "attitude" is one of C89
plus C99 features.  I haven't seen commercial embedded compilers seeking
to regard as undefined any behaviors that had been defined in C89.

The memory manager included in a typical RTOS will allow for storage to be
used as one type, and then recycled for use as another type, initially
holding Unspecified Value of that latter type, without requiring that the
storage be overwritten between uses in cases where the later user doesn't
care about the bit patterns contained therein.  Any memory manager which
provides such semantics without scrubbing storage *must* rely upon
guarantees beyond those given in C99 or C11 because those versions of the
language define Effective Type semantics which would cause any read of
storage using a type other than the one used to write it as yielding
Undefined Behavior rather than an Unspecified Value.

Under C89, given:

    union { int i; float f; } u;
    int *ip = &u.i; float *fp = &u.f;

Writing u.f and reading u.i would yield an Unspecified Value, except on
implementations where "int" could have trap representations, and nothing
in C89 would indicate that the semantics of writing *fp and reading *ip
would not match those of accessing struct members directly.  The guarantee
that writing as one type and reading as a type with no trap representations
would at worst yield an Unspecified Value is essential to facilitate
efficient memory managers.  C89 provided that guarantee; C99 and C11 do not.
Because C is used for many purposes which do not require the ability to
handle efficient mixed-type memory pools in user code, the C99 and C11
Standards do not require implementations to provide everything needed for
such pools to be implemented in user code.  Any application requiring the
implementation of such pools in user code will thus require guarantees beyond
those given in C99 or C11.

I think you mean "gcc -fno-strict-aliasing", which forces the compiler to
support C89 semantics which it otherwise would not.  The language processed
without that flag is not suitable for embedded use.
