__DYNAMIC_REENT__ part of external API?

[Jonathan S. Shapiro]

If I build a version of newlib with __DYNAMIC_REENT__ defined at the
time of build, does __DYNAMIC_REENT__ also need to be defined when
client code (i.e. code that calls newlib) is compiled?

The only use (consumption) of __DYNAMIC_REENT__ that I see in the
newlib headers is in libc/include/sys/reent.h, where it wraps an
extern declaration of __getreent(). Offhand, I don't think that entry
point needs to be generally available to clients.

Advice/input?


Thanks
