[fpc-pascal] FPC in DOS environment

[Daniel Franzini]

for now, on MS Virtual PC with fpc2.0.5 stable for go32v2, the IDE
does not even get loaded correctly...it displays some info on compiler
and ide version, shows the nice FP screen and then exits quickly...i
will try to recompile from the sources with debug info to see exactly
where it stops (altough i'm no gdb expert)

not sure if this is a problem of freedos or virtual pc buggy DPMI or
some kind of combination of these two

when i get home, i will try on a real machine with freedos and with
real DOS (if i manage to find my diskset)
