But, gdb is passing /home/boyde/prj/ncurses/build/objects/../../test/cardfile.c
to open as confirmed by:
 1469 83266416 [main] gdb 1006 _open: open
(/home/boyde/prj/ncurses/build/objects/../../test/cardfile.c, 0x10000)

Later we see

  201 83270897 [main] gdb 1006 mount_info::conv_to_win32_path:
d:\Cygwin-1.1\hom
e\boyde\prj\ncurses\test\cardfile.c(rel),
d:\Cygwin-1.1\home\boyde\prj\ncurses\t
est\cardfile.c(abs) 0x2(flags) = conv_to_win32_path
(/home/boyde/prj/ncurses/bui
ld/objects/../../test/cardfile.c)

which indicates that the path was converted correctly, once.


It appears, and I'm not used to looking at strace, that gdb is opening
cardfile.c a second time with the same path as above.  It's this second open
that isn't correct.

Cheers,
