I don't know if its important but it gives the user features like accessing
previous input (C-p) and to send signals to the inferior (although this can
probably be done from the GUD buffer).

There appear to be two problems:
1) gdb-ui doesn't output to the I/O buffer in NT.
2) cat might not exist in NT.
To solve 1) I propose to get rid of the I/O buffer in NT. Then 2) would
no longer be an issue as cat (or hexl) would not be needed in NT. To do this
(and cover Windows NT/2K/9X/ME?) what case should I consider?
(eq system-type 'windows-nt)?
(memq system-type '(ms-dos windows-nt))?
something else?
