This patch is a preparation for the upcoming change making use of
the built-in static_assert(), which is available since C11.
When using built-in static_assert(), gcc v12.2.1 fails:
include/osmocom/core/msgb.h: In function 'msgb_alloc_headroom_c':
include/osmocom/core/msgb.h:532:33: error: expression in static assertion is not constant
532 | osmo_static_assert(size >= headroom, headroom_bigger);
include/osmocom/core/utils.h:86:24: note: in definition of macro 'osmo_static_assert'
86 | static_assert((exp), "(" #exp ") failed")
| ^~~
include/osmocom/core/msgb.h: In function 'msgb_alloc_headroom':
include/osmocom/core/msgb.h:554:33: error: expression in static assertion is not constant
554 | osmo_static_assert(size >= headroom, headroom_bigger);
include/osmocom/core/utils.h:86:24: note: in definition of macro 'osmo_static_assert'
86 | static_assert((exp), "(" #exp ") failed")
| ^~~
These are not really *static* assert()s, because they operate on the
user supplied arguments 'size' and 'headroom', which are not guaranteed
to be integer literals. Neither they trigger compilation failures
as expected, nor do they abort at run-time. They simply do nothing.
