[Bug-glpk] v4.15 - gcc warns about trigraphs

[Robbie Morrison]

Hello GLPK bug list

A very minor issue with 4.15.  I didn't supply a patch because
hand editing would be as fast.

best wishes to all
Robbie

ISSUE

date     : 06-Mar-2007
summary  : gcc warns about possible trigraphs when building libs/glplpx14.o
severity : trivial for gcc, sightly more significant on compilers where
           trigraphs are enabled by default
src file : src/glplpx14.c
fix      : replace message string "(???)" with "(\?\?\?)" in five places
explain  : the sequence ??) will stand for ] if trigraphs are enabled
