Sorry for the confusion. The version is indeed 2.91.66.
For some reason, it seems to be referred to as gcc-295
within our organization ...

Ok, looks like our system admins have not updated it, then.
Anyway, I found a workaround (see below).

I had installed gcc on our systems a few months ago, and everything
went through fine. The, about a month ago, our network changed as
part of a re-org, so I had to re-do it again.

When I compared the contents of the old and new gcc installation
directories, I found that the old one had "time.h" and "sys/time.h" 
files, whereas the new one had only "time.h" and "sys" directory
with other files. When I copied the old "sys/time.h" file to the
new location, everything worked fine.

So, one of two things happened:
- My installation was messed up by someone
- I ran the gcc compilation on a machine which did not have a
  good version of /usr/include, which led to gcc not creating
  the sys/time.h file, thinking it was ok to use the system's
  version instead.

When I applied the above workaround, all problems went away, including
the algo.h problem. Now, I cannot seem to reproduce it, but that is fine,
because I can proceed with my compilation.

Thank you very much for your help !
