When using MSVC-2015 to build the tests/unistdio/test-ulc-*.c files,
I get ASSERT() on all the '%a' formats. E.g. in
unistdio/test-ulc-vasnprintf1.exe
and unistdio/test-ulc-printf1.h (line 195):
char *result =
my_xasprintf ("%a %d", 3.1416015625, 33, 44, 55);
ASSERT (result != NULL);
ASSERT (strcmp (result, "0x1.922p+1 33") == 0
|| strcmp (result, "0x3.244p+0 33") == 0
|| strcmp (result, "0x6.488p-1 33") == 0
|| strcmp (result, "0xc.91p-2 33") == 0);
The 'result' I get is '0x1.9220000000000p+1 33'.
The MSDN at:
https://msdn.microsoft.com/en-us/library/hf4y5e3w.aspx
isn't clear on how many digits there should be, but I guess the precision
is a reflection the double float-type.
With "%.3a %d", I do get the expected "0x1.922p+1 33".
So are these tests somewhat gcc-centric or what?
