2952	Windows: path.glob doesn't accept paths at the root of the current drive	John <jwbito@…>	Vladimir Prus	"Trying to provide a full pathname to boost-build caused [[BR]]
error: Unknown target type EXE[[BR]]
The problem occurs with[[BR]]

{{{
boost-build /temp/boost-build ;
}}}

Based on the debug output the leading slash of the pathname is removed in util/path.jam:
{{{
/temp/boost-build/util\path.jam:54:>>>>|>>>>|>>>>|>>>>| native-NT /temp/boost-build/tools/types/*.jam
/temp/boost-build/util\path.jam:464:>>>>|>>>>|>>>>|>>>>|>> MATCH ^/?(.*) : /temp/boost-build/tools/types/*.jam
/temp/boost-build/util\path.jam:464:>>>>|>>>>|>>>>|>>>>|>> local result = temp/boost-build/tools/types/*.jam
/temp/boost-build/util\path.jam:465:>>>>|>>>>|>>>>|>>>>|>> regex.split temp/boost-build/tools/types/*.jam /
}}}
While the equivalent

{{{
boost-build c:/temp/boost-build ;
}}}
is processed successfully. Note that the boost-build kernel is loaded using the path specified in either case, up to the point of loading the contents of tools/types/."	Bugs	new	To Be Determined	build	Boost.Build-M3	Problem
