Description of problem:

Hello there,

I have just tried to compile package gimp-1.2.3-9 from Redhat 8.0

I got the following message from the compiler.

cc: Warning: imap_preview.c, line 167: In the initializer for avg, the expression "(299**colour+++587**colour+++114**colour++)/1000" modifies the 
variable "colour" more than once without an intervening sequence point.  This behavior is undefined. (undefvarmod)

Here is an untested patch to shut up the compiler.

./plug-ins/imagemap/imap_preview.c.old ./plug-ins/imagemap/imap_preview.c

Additional info:


compaq compiler is not significant. GNU Compiler could 
probably also produce this error message with -Wall.
