Attached is the output of "gcc -ansi -dM". I hope it contains enough information to answer your questions. Note also that _REENTRANT is not defined here, therefore its source must be somewhere outside of gcc.
I've been trying to reproduce this using HP's test drive machines, unfortunately they all use single-threaded gcc :-(
From all that's been said it's apparent that _REENTRANT is getting set by one of the gcc headers, but which one? This is important because we have a consistency problem otherwise (threading support getting turned on depending on which headers you happen to have included).
All of the libstdc++ headers will end up including gthr-default.h which will define _REENTRANT. This is planned to be fixed (see PR 11953) but I don't know when, possibly 4.0 now. Shouldn't the attached header test __osf__ not __osl__ ? jon -- "There are only two industries that refer to their customers as 'users'." - Edward Tufte
