Has anyone used gcc with -g -pg -fprofile-arcs -ftest-coverage?
I get series of msgs like

arc profiling: Can't open output file /c/LASER/utplus/mpeg7/SOURCENAME.da.

upon exit(EXIT_SUCESS) from main() and the *.da files are not
created. The SOURCENAMER.{bb,bbg} files are created (upon
compilation?).

My gcc -v is:

$ gcc -v

(BTW, I get

Compiling ../../cube/common/CException.c to CException.o

while compiling one of the objects; so I compiled it with -g -pg
only, ommiting -fprofile-arcs -ftest-coverage - could this be the
source of my problem? BBTW, Compiling without -mno-cygwin gives
the same result.)
