[PATCH newlib 0/1] sys/signal.h needs sys/_intsup.h

[Joel Sherrill]

Hi

The recent addition of the sig2str block of code for definitions and 
prototypes resulted in the following one line program not compiling
for RTEMS targets:

#include <sys/signal.h>

Turned out that __STDINT_EXP used to conditionalize the definition
of SIG2STR_MAX isn't defined unless <sys/_intsup.h> is included.
I guess the test code got lucky.

It's a simple patch that needed more background and investigation
than code.

Is it safe to assume that including each POSIX and Standard C Library file
independently should compile? If so, I will file a ticket to at least at
those to the RTEMS compile only tests like the ones we have that check
a method can be used per the specific includes in the POSIX specification.

Sorry this slipped through.
