Subject: ANN: gcc diagnostic output (troubleshooting tool)

Hello Cygwin-List,

I have written a Perl script that outputs this* from my just-installed 
version of the latest Cygwin gcc release. I would like to know if this 
(sort of output) is useful to users as a means of more quickly and clearly 
seeing what the setup defaults of the gcc system are when one is having 
trouble diagnosing one's own (or someone else's) build hang-ups. If there's 
no suggestion that something is missing from the output of this that 
experts would normally want to see, etc., then I will release it (I'll 
announce to this List how readers can download it).

*Below is the output. Sorry that emailers will probably wreck it by 
wrapping, nothing much to be done about that. I suggest for those who want 
to examine it closely, that using a mono font to do so might be helpful.

--- command in Cygwin sh (aka bash.exe): ---
$ perl -S gcc_spec_check.p D:/Cygwin/bin/gcc.exe

Please note that I am, this seems to show,  getting `as'  errors similar to 
what was reported by the fellow who is trying to build Compress::Zlib for 
Perl. I don't get this happening when I run this very same script on my 
MinGW gcc-2.95.2. BTW, if someone running Linux or some other Unixen 
would offer to test my Perl script before I release it, I would appreciate it. 
Otherwise, I'll just go ahead and embarrass myself as usual :-).

Thanks for the input/attention/patience,
