As no one complained, I changed 28_strings.c to use ISO C functions and reintroduced 24 and 28 tests in Makefile for Windows.

round and several other floating point functions from math.h were not working on windows for some years, and around November 2015 I fixed most of those issues. However, I wasn't aware that some tests were disabled on windows due to the missing functions. Good catch (I'd leave it to you to re-enable them).

Hi again,


I see from test/test2/Makefile that 24_math_library is removed for Windows because of lack of round().


ifdef CONFIG_WIN32

SKIP += 24_math_library.test # don't have round()


With mob compiled with a recent MinGW gcc compiler.

This test is fully working. Can you reconsider to add it as part of standard tests suite.


I also note that 28_strings is removed because Windows lacks index/rindex (which is true).

Now, if you remove <strings.h> which was a BSDish include now removed from POSIX and replace

   printf("%s\n", index(a, 'o'));

   printf("%s\n", rindex(a, 'l'));

   printf("%d\n", rindex(a, 'x') == NULL);


By iso C equivalent functions:


   printf("%s\n", strchr(a, 'o'));

   printf("%s\n", strrchr(a, 'l'));

   printf("%d\n", strrchr(a, 'x') == NULL);


It works on Windows and should work on any system.
