compiling xgrass libraries

Greetings fellow users

I'm having troubles compiling the xgrass libraries. I'm using

gcc -ansi -O (plus include paths)

for my compiler options. In the file $GISBASE/src/include/MatrixP.h it has
trouble parsing the structure on lines 253-257 and 416-418.

Does anyone have any insight on what can be done to fix this?
