Building on SGI with IRIX 6.2

[Ben Elliston]

   I'm trying to build Sourcenav 4.5.2 on an SGI Indigo 2 workstation
   running IRIX 6.2. I had no success using SGI's compiler, but did get a
   lot farther with gcc (version 2.8.1).

Is the configure script locating SGI's shipping version of lex?
If you install GNU flex does the problem go away?
