It works correctly for me, and the patch makes no sense - if the compile test fails, then the compile and link test should also fail (which it does for me).

I'm using autoconf 2.67, but I'm not aware of anything that should cause problems with the stated required version (2.52).

Thanks for investigating, in the meantime we found out that it has to be some CFLAGS/LDFLAGS combination causing the error. If it's some valid combination causing the problem the reporter will report and reopen this bug.

Thanks for updating this bug, much appreciated.

Indeed, if you do established a sane set of flags that reproduces the problem, I'll be happy to investigate.
