[Scip] Issue compiling SCIP with gcc 4.1.2

[Stefan Vigerske]

Hi,

in src/scip/pub_misc.h, line 4976, try to replace
#define SCIPisFinite isfinite
by
#define SCIPisFinite(x) isfinite(x)

If that works, please let me know.
If that does not work, try replacing the same line by
#define SCIPisFinite finite

If that does not work, replace the same line by
#define SCIPisFinite(x) ((x) == (x))

Stefan
