The top level configure script may do, but as Daniel says the GDB 
sources do not.

Look at www.mingw.org for GDB MinGW patches (GDB 6.3-1 last time I 
looked). These will get it to compile for MinGW, but, even if they can 
be made to cross compile, Daniel's point about remote debugging still 
stands. I can see why you wouldn't want to use Windows as a build 
platform, but I suggest that, unless you have a good reason not to, you 
debug the programs natively using the native MinGW GDB. You can probably 
download a binary from their website along with the rest of MinGW/MSYS.

Alternatively, the GDB in Cygwin (www.cygwin.com) is capable of 
debugging MinGW programs. Cygwin also has support for compiling them 
with 'gcc -mno-cygwin'. Note that the standard Cygwin install does not 
include developer tools, but the installation tool is quite easy to use.
