-----------------------------------------------------------------
Key: XALANC-569
URL: http://issues.apache.org/jira/browse/XALANC-569
Project: XalanC
Type: Bug
Components: XalanC
Versions: 1.10
Environment: 32-bit Solaris & HPUX
Reporter: Ashley Zinyk

The following error occurs while compiling DoubleSupport.cpp on Solaris:

The problem was introduced in XALANC-511, which introduces a compile-time check
to verify that the platform has IEEE754 (standard floating point) support.
