I've been encountering some problems using gprof (GNU gprof (GNU Binutils) =
2.24.51.20140623) in the most recent cygwin (32 bits) . Basically gprof see=
ms to be missing static functions calls in the flat profile report. For the=
 attached source file (compiled with -Wall -g -pedantic -std=3Dc99 -pg -O0)=
 if I disable the USE_STATIC macro the flat report seems ok.=20

But if I enable it (making those functions static) I get pretty weird resul=
