I have tried with the latest commit 7e4fc3a0d01173575b3b29f71ae4da87322ba14b
the following configuration setting
./configure --extra-cflags='-std=c99'
just for the sake of experimentation and have found there's a problematic
behavior which probably is my fault, but have no idea what am I doing wrong
here...
My command is:
make clean && make -j4 && make test
During the test, it returns the following error message:
make[1]: Entering directory
'/home/stefanos/repositories/active/tinycc/tests' ------------ version

libtcc_test_mt.c: In function ‘sleep_ms’:

make: *** [Makefile:457: test] Error 2
I opened tests/libtcc_test_mt.c file and saw there's a <unistd.h> header file
which is responsible for `usleep()`.
To verify it got parsed as expected, I run
tcc -E -P tests/libtcc_test_mt.c | grep usleep
which indeed it returned
extern int usleep (__useconds_t __useconds);
The same error remains as it with `-std=c11` too.
Can someone help me figuring out what am I doing wrong here?
