Follow-up Comment #4, patch #8847 (project autoconf-archive):
Hi Will,
The -mt flag is being passed to the compiler, yet _REENTRANT is not implicitly
defined?
I'm going to need more information on this, because this does not appear to be
correct behavior for the Solaris vendor compiler. From the cc(1) man page on
one system I have here:
-mt Passes D_REENTRANT to preprocessor. Appends -lthread.
If you are doing your own multithread coding, you must
use this option in the compile and link steps. To
obtain faster execution, this option requires a mul-
tiprocessor system. On a single-processor system, the
resulting executable usually runs more slowly with this
option.
Do the docs for your compiler version describe something different? Is there a
new flag that needs to be supported, perhaps?
