[Coin-discuss] -pedantic-errors incompatible with #warning

[bremner at unb.ca]

There seems to be some internal disagreement about how strict the 
C++ standard compliance checking should be.

The following is true in the versions of Cgl and BuildTools checked
out today from svn via SYMPHONY/stable/5.1.

From the Externals file: 
BuildTools https://projects.coin-or.org/svn/BuildTools/stable/0.5
CoinUtils    https://projects.coin-or.org/svn/CoinUtils/stable/1.0/CoinUtils


In BuildTools/coin.m4, cxx_warn_flags contains -pedantic-errors

In CoinUtils/src/CoinSignal.hpp, there are several usages of #warning

This causes gcc-4.1.1 on Solaris Intel to fail to compile
Clp/src/ClpSolve.cpp and report the #warning's as errors.

I would recommend either replace -pedantic-error with pedantic, or 
replace #warning with #error if that is what you want.

Of course, perhaps the CoinSignal should recognize gcc/Solaris-intel,
but that is a different question.
