RE: [ECOS] eCos compatible with arm-elf-gcc version 4.1.1?

[C B <csb_80@hotmail.com>]

Disregard.  Something within my cygwin installation was corrupted.  Re-installing cygwin solved whatever the issue was.

> It seems that for some reason (only when I try to build with arm-elf-gcc version 4.x) I get these errors that it can't find the source files but it's trying to include the unix style filesystem /opt/ecos rather than than /ecos-c/cygwin/opt/ecos that is also included in some cases. Any idea where configtool is getting these paths or why it might differ for gcc4.x? The files are there and my ECOS_REPOSITORY is properly set but I can't determine from where the reference to /opt/ecos is originating.
