Well, the last version of Cygwin (1.1.2) is wonderful ! After 2 hours of hard-disk movement, in a pentium 200 with only 64Mb and, INCREDIBLE, Windows 95/OSR2, I can compile my project RTEMS for SH1/2 !!! Nothing bash crash, cat crash or #$! crash, all work fine !!! I'm so happy which I can stop my work and go to the beach !!!
