Problem: warnings from system headers that are hard to eliminate.
#define min(a,b) ((a)>(b)?(b):(a)) #include <stdlib.h> #include <stdint.h>
Compile it and observe the warnings:
pgcc -c x.c PGC-W-0221-Redefinition of symbol min (C:/mkl/cache/pgi/15.5/Microsoft Open Tools 12/include\stdlib.h: 922) PGC-W-0221-Redefinition of symbol SIZE_MAX (C:\mkl\cache\pgi\15.5/win64/15.5/include\stdint.h: 270) PGC/x86-64 Windows 15.5-0: compilation completed with warnings
Both warnings should be fixed by wrapping the ‘Redefinitions’ with #ifdef.
The SIZE_MAX warning goes away if stdint.h is included before stdlib.h, which a large source base cannot always guarantee.
I would be much obliged to you if you check and let me know if the issue reproduces, and whether it has already been fixed in later release of PGI compilers.
