Buildung Tools for m68k-RTEMS 4.6.99.3 on Cygwin Host

[frank.ueberschar at dsa-volgmann.de]

Hallo Ian, 

installing MSYS and MinGW seems to be the 
good way for us. We were using RTEMS 4.5.1 
for years compiling on cygwin. 

My conclusion after a few days of reading 
Howtos and trying is to have left an installation 
of cygwin (at least for bootstrapping rtems and
compiling the old apps) and a working MinGW 
installation too. 

Compiling rtems 4.6.99.3 for m68k seems to work
on the MSYS environment having installed the 
pre-build compilerset from pub/rtems/windows. 

Bootstrap on MSYS does not yet work for me 
as a newer version of automake(1.10) is needed. 


Thank you for your help. 


Regards, 

Frank
