Cross-compiling PARI with mingw on Linux

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Hello PARI-dev,

This is a summary on how I can cross-compile PARI with mingw and test the
result on Debian (for ix86 and amd64) 

You need to install the Debian packages mingw32 and wine.
You need the attached script "runwine" (trivial wrapper around wine).

1) run Configure as follow:
RUNTEST=/path/to/runwine CC=i586-mingw32msvc-gcc ./Configure --host=i586-mingw
2) compile:
make gp -C Omingw-i586
3) test:
RUNTEST=/path/to/runwine make bench -C Omingw-i586
(every test but program-sta.dif should pass).

Cheers,
Bill.
