Hi All I am trying to compile gcc-4.3.0 on AIX 5.3. I sent CONFIG_SHELL to bash, did configure and when I do a make I get the below error and the make aborts : sed -e 's/@gcc_version@//' < > mkheadersT /usr/bin/bash: -c: line 0: syntax error near unexpected token `>' make: The error code from the last command is 2. It is always in fixincludes directory. I tried to download gcc 4.2.3, but the same error. Any one tried to compile gcc on AIX successfully. I would very much appreciate your help. With Regards Vardhan
