After an SVN update my user-config.jam is now producing no end of errors:

using gcc : cygwin ;

Produces:

M:/data/boost/trunk/tools/build/v2/tools\gcc.jam:106: in gcc.init from 
module gcc
error: toolset gcc initialization:
error: version 'cygwin' requested but 'g++-cygwin' not found and version 
'3.4.4' of default 'g++' does not match
error: initialized from C:\cygwin\home\john\user-config.jam:40

And:

using gcc : cygwin4 : g++-4 ;

Produces:

M:/data/boost/trunk/tools/build/v2/tools\gcc.jam:77: in gcc.init from module 
gcc

error: toolset gcc initialization:
error: provided command 'g++-4' not found
error: initialized from C:\cygwin\home\john\user-config.jam:41

Even though the command g++-4 most certainly does succeed!

And:

using gcc : mw4 : "set PATH=C:/MinGW/bin;%PATH% && C:/MinGW/bin/g++.exe" : 
<linkflags>-enable-auto-import ;

Produces:

M:/data/boost/trunk/tools/build/v2/tools\gcc.jam:77: in gcc.init from module 
gcc

error: toolset gcc initialization:
error: provided command 'set PATH=C:/MinGW/bin;%PATH% && 
C:/MinGW/bin/g++.exe' not found
error: initialized from C:\cygwin\home\john\user-config.jam:43

While again, the command does actually work.

Ideas?

Cheers, John.
