In confdefs.h we have:

[...]
   #ifdef RTEMS_POSIX_API
     #if !defined(CONFIGURE_MAXIMUM_POSIX_THREADS)
       #define CONFIGURE_MAXIMUM_POSIX_THREADS \
         rtems_resource_unlimited(CONFIGURE_UNLIMITED_ALLOCATION_SIZE)
     #endif
     #if !defined(CONFIGURE_MAXIMUM_POSIX_MUTEXES)
       #define CONFIGURE_MAXIMUM_POSIX_MUTEXES \
         rtems_resource_unlimited(CONFIGURE_UNLIMITED_ALLOCATION_SIZE)
     #endif
     #if !defined(CONFIGURE_MAXIMUM_POSIX_CONDITION_VARIABLES)
       #define CONFIGURE_MAXIMUM_POSIX_CONDITION_VARIABLES \
         rtems_resource_unlimited(CONFIGURE_UNLIMITED_ALLOCATION_SIZE)
     #endif
/*
