[Mono-list] System.Data Linux Compilation Error

I came across this odd error compiling the mcs module tonight (fresh cvs
update).  Maybe it's just me...

When compiling System.Data, I got an error that it couldn't find the
Mono.Data.Tds assembly.  This was from the mcs/class/System.Data
directory, running the command:

	MONO_PATH=../../class/lib: mono ../../mcs/mcs.exe --target
	library --noconfig -L ../../class/lib: -o
	../../class/lib/System.Data.dll -r corlib -r System
	-r System.Xml -r System.EnterpriseServices -r Mono.Data.Tds
	@.response

Further examination allowed me to compile System.Data if I added the
following parameter to the mcs command:

	-lib:../../class/lib

So, I figured I'd try to fix up the `library.make' file to insert the
`-lib' parameter to mcs.

Trying my fix resulted in the same compiler error -- it couldn't find
the assembly Mono.Data.Tds.  Further inspection showed that the command
my changes made to `library.make' had an extra `:' appended to the -lib
parameter, e.g.:

	-lib:../../class/lib:

The extra `:' prevents mcs from finding the assembly.  I find this to be
an mcs bug.  (I haven't looked into this any further.)

Thus, my final patch inserts an appropriate -lib parameter if
$(MONO_PATH_PREFIX)$(MONO_PATH) is non-null, and strips off the final
`:' if present.

After applying my patch I'm able to compile System.Data; however, I get
a System.InvalidCastException while compiling Mono.Data.MySql.dll. 
However, I get the same exception without my change, so they are not
related.

Suggestions?

Thanks,
 - Jon
