Buglet in gcc 1.36 (or in install docs)
Bennett Todd
According to the installation docs:
5. Build the compiler. Just type `make' in the compiler directory.
Ignore any warnings you may see about ``statement not reached''
in the `insn-emit.c'; they are normal. Any other compilation
errors may represent bugs in the port to your machine or
operating system, and should be investigated and reported (*note
Bugs::.).
I hadn't made any changes to the Makefile. I used "config sun3-nfp".
I got the following errors, which seem to be due to the GNU stab setup
using an enum, as far as I can tell:
cc -c -g -I. -I. -I./config dbxout.c

"dbxout.c", line 982: warning: enumeration type clash, operator =
"dbxout.c", line 1049: warning: enumeration type clash, operator =
This appears to be an unimportant warning. Either the code should be
changed to make it go away, or the installation docs should mention that
this is another benign error that may be ignored.
To the best of my knowledge I haven't make any changes to the system
software that would break the compiler or change the compilation
environment. Here's a script output that starts in a directory freshly
tar extracted from the archive I FTP-ed off prep.ai.mit.edu; I edited it
to remove control characters (^M at end-of-line and some spurious ^H
chars that bash threw in) and to explicitly break very long lines.

Please let me know if there is any more info I could provide. I don't
know if this has already been reported; I was on info-gcc and bug-gcc
for a very short while; I asked to be put on, I got messages for a
couple of days, and then I didn't see anything more. I assume I've been
removed from the mailing list for some reason. If someone could put me
back on the info-* and bug-* lists for the GNU software I'd appreciate
it, as I am doing my best to install and support all of it on our
systems.
