[Fwd: Re: gcov in cross-compile: have a patch, seek direction]

[Danny Backx]

Here's the patch that I incorrectly sent to thw wrong list earlier.

As I wrote below, comments are welcome.

Proposed ChangeLog entry :
2007-05-16  Danny Backx  <danny.backx@scarlet.be>
	* doc/gcov.texi : Add description of new compiler command line
	option -fcoverage-base.
	* toplev.h (-fcoverage-base, coverage_base) : Add new command
	line option and variable.
	* coverage.c (build_gcov_info) : Add code so the new variable
	overrides the directory name used to store coverage files.
	* common.opt : Add declaration for new command line option.
	* libgcov.c (gcov_exit) : call another error handler than stderr
	when running on Windows CE.

The last entry is not really part of the new functionality. I would
rather expect a comment to either remove this or to propose this as
another patch entirely.

	Danny
