As there is no changelog here, let me ask a (maybe stupid) question.
What is your goal of diverting from GCC extensions and switching
to the C11 standard?
Do you want the codebase under CodeSamples/ to be strictly
conformant to C11 or later?
Runnig "make" under CodeSamples/count, with "-std=c11" appended
to GCC_ARGS, I get a lot of compile errors/warnings (with GCC 9.4.0
under Ubuntu 20.04), beginning with:
cc -g -O2 -Wall -std=c11 -o count_atomic count_atomic.c -lpthread
In file included from /usr/include/sched.h:34,
from /usr/include/pthread.h:22,
from ../api.h:159,
from count_atomic.c:22:
/usr/include/time.h:113:5: error: unknown type name 'locale_t'
113 | locale_t __loc) __THROW;
| ^~~~~~~~
A workaround is to append "-D_GNU_SOURCE" to GCC_ARGS. With that,
I get the next warning of:
../api.h:766:2: warning: implicit declaration of function 'typeof' [-Wimplicit-function-declaration]
766 | typeof(*ptr) _____actual = (o); \
Apparently, typeof() is another GCC extension. __typeof__() might
be used instead, but it is not ISO C.
So what is you goal of these switches?
Thanks, Akira
