Hello
Currently, on mingw32, call graph info generated with -pg switch and gprof is
virtually useless on mingw because there is no info for main().
For some reason (I can't find the commit in the Changelog) the Cygwin
version of SUBTARGET_PROLOGUE was disabled for mingw32.
Whatever the bug that was present, it appears to be gone now and using
the Cygwin definition works just fine.
Hence:
ChangeLog
2002-12-04 Danny Smith <dannysmith@users.sourceforge.net>
* config/i386.mingw32.h (SUBTARGET_PROLUGUE): Don't disable
the Cygwin definition.
