Package: lintian
Severity: wishlist

A lot of libraries are not compiled with -D_REENTRANT unfortunately.

The presence of the symbol '__errno_location' in the shared library
could be used as an indication of compilation with -D_REENTRANT.

The presence of the symbol 'errno' in the shared library is the
indication of compilation without -D_REENTRANT and should be an error.

(see /usr/include/bits/errno.h for explanation).

If neither symbol are defined, then we cannot tell, but the presence
or absence -D_REENTRANT is probably harmless then.

Phil.

This long-term wishlist request came up at Debconf and we determined that
compiling with -D_REENTRANT is only required to make some particular
symbols available from the glibc header files, and doing a grep of the
current header files, it looks like getlogin_r is the only affected
symbol.  I'll file a Policy bug to remove the policy requirement.  It
doesn't look like a lintian check would be useful.
