flexfax: cannot compile libtiff

[Kit-pui Wong <kpwong@psy.cuhk.edu.hk>]

Dear All,

I eventually got libtiff (time stamp: April 30, 1996)
but it failed to compile on IRIX 6.5 with gcc 2.8.1.
The error log is shown in appendix.

Is it asking for OpenGL package ?
May you tell me how to solve this error ?

Please drop a copy to my email address should you
have any hint, I didn't subscribe to the mail list

Many thanks in advance!
KiT
