Martin Sebor resolved STDCXX-873.
---------------------------------
Resolution: Fixed
Turns out the problem is caused by the GNU libc headers which make use of the
{{long long}} type. Since we compile with the EDG eccp -A option for strict C++
98 conformance the compiler errors out on the {{long long}} type in all config
tests that #include such headers. The fix committed in
[rev648332|http://svn.apache.org/viewvc?rev=648332&view=rev] suppresses the
error during the configuration process.
Here's the command line and the compiler output for the config test for
{{wcslen()}}:
{noformat}
