Hi, All ! I have just successfully compiled msp430-gcc using MinGW and MSYS.
For those who want to do the same, please note: You need to patch gcc-core sources before makeing gcc, otherwise I will not compile under MinGW. The patch was posted to this mailing list by Andrew Schwarz in the September 2002. Then follow instructions for building msp-gcc under linux. All the best ! Oleg.
