X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8ab40e70518402071f50263ebae8cf9633500405;p=quix0rs-gnu-social.git

Cleanup for bug 1813: workaround sometimes-missing dl() in PHP 5.3 by defining our own bogus function rather than attempting to patch upstream libs. This keeps our fix across upstream versions (or when loading upstream library from outside extlib)

Note that fixes to OpenID libraries in commit fe9473ac7810d317e001a0fec19cbacaafc0c909 were lost in just such an update.
