Make check - test-vasprintf-posix failure - darwin12 - macos

Hello,

I'm trying to compile M4-1.4.19 on macOS, and I ran :

./configure
make
make check

Actually, make check is failing on test-vasprintf-posix.
After investigating, I found that they are 3 tests that are failing, about pseudo denormal (you can find the four tests by looking for "{ LDBL80_WORDS (0x0000, 0x83333333, 0x00000000) }".

Only the first one pass, the three next are failing.

First question: are those tests important?

For help with investigation, I found that by replacing 0x83333333 to 0x63333333 will make the tests pass, but I don't know what the impacts are as I'm absolutely not a C developer.

Note:

After reading here: https://lists.gnu.org/archive/html/bug-m4/2013-06/msg00000.html I also tried running ./configure gl_cv_func_printf_directive_a=no, but no chance of making it working.

The only solution I found is by commenting the three last tests about Pseudo-Denormal directly in tests/test-vasprintf-posix.c

Thanks a lot
