Just tried to build gdc on Solaris 10 x86, looks like it has some problem with bool.  Anyone know a quick fix (maybe just some flags)?

bash-3.00$ uname -a
SunOS unknown 5.10 Generic i86pc i386 i86pc

bash-3.00$ which c++
/usr/sfw/bin/c++

bash-3.00$ c++ -v

detail error message (cannot post togather with the previous one)
