+ Also note that on some installations of CygWin, one of the system
+ header files used the proprocessor to define quad
to
+ quad_t
. Since deal.II uses the name
+ quad
as a function name, the name is sometimes
+ replaced, sometimes not, depending on the order of include files and
+ whether the respective system header was included at all. This leads
+ to compilation errors.
+
+ Since the offending preprocessor define is only active when
+ _POSIX_SOURCE
is not set, deal.II
+ releases after version 3.4 set this flag, to avoid the
+ problem, but releases up to and including version 3.4 may not
+ work. For more information, refer to the
+ mailing list
+ thread on this subject, and follow-up messages.
