Jakub et al - The attached patch fixes bug 58312, by replacing the runtime check of vsnprintf with a compile-time check -- which means that it now performs the same checks for both native and cross compilers, ensuring consistency instead of the previous behavior of just discarding some libssp functions when cross-compiling.
I've tested this by reconfiguring (on an x86-linux cross
configuration) and confirming that it behaves as expected -- the
HAVE_USABLE_VSNPRINTF macro is defined in confdefs.h, and the
config.log has verbosity of output similar to the previous version.
(The formerly-explicit output is included as part of the AC_CHECK_FUNC
macro.)
It is possible that this will enable the macro on some native
configurations where vsnprintf was present but is broken. The effect
is simply that a few additional functions (which rely on vsnprintf)
are compiled into libssp; this seems relatively innocuous.
Jakub, I'm cc'ing you in hopes that you're a reasonably appropriate
person to review this.
Ok for trunk?
Thanks,
- Brooks
