Re: [Xotcl] NX on windows

The problem with the compile below is very wierd. The key is
in the following line where cpp (the c pre-processor)
complains about an invalid argument

../../sources/tcl8.5/win/../generic/regcustom.h:33:20:
error: ../../sources/tcl8.5/win/../generic/tclInt.h: Invalid
argument

The "invalid argument" is strange, because it does not say
at all, what the problem is (gcc is normally more specific).
This message is a generic error message from c-library. Some
more investigation revealed that the problem has to do with
the size (!!!) of tclInt.h. Shortening it to e.g. 126785
bytes lets cpp process it (but of course, later other
problems occurred). I had the sources on the host and
mounted it from the windows environment in the vbox, and
assigned it to the drive letter "y:".

Copying the full tree to "c:" solved this issue. Very weird.
After digging into tcl's platform specific defines it took
me quite a while to start to distrust cpp. Not sure, whether
this is a bug in cpp, win7 or vbox, but i am posting it here
in the hope, that maybe someone who runs into the same
problem might google it and save some time.

On drive c, compilation of tcl and tk worked perfectly
(tried tcl 8.5.12).
