seentree.c: In function `tcl_killseen':
seentree.c:202: error: `context' undeclared (first use in this function)
Reason: wcc removed context debugging completly
Solution: go through the source code of the module and remove ALL calls to 'Context;' / 'context;'. After that the module should compile again (except if you still need to adjust the Makefile reflecting changed header filenames).
read in Mafefile or Configure script, but never really looked what it does and so I have no clue how to filter it out ^-^. But how you remove it, is everyones own decition .
