RE: [PATCH 2/2] Do not use DOS paths on Cygwin

[Pavel Fedin]

 Hello!

> In that case, we need to fix 'abspath', not disable this feature.

 I have came up with another implementation, currently testing it.
 My new implementation should allow DOS and UNIX paths to coexist. However
there's still two differences:

1. abspath on Cygwin returns UNIX-style paths and on pure DOS/Windows -
DOS-style. If DOS-style absolute path is already supplied, it will leave it
as is.
2. PATH_SEPARATOR on Cygwin is ':' and on pure DOS/Windows is ';'.

 In order to distinguish between these two i have added one more test to
configure. It attempts to compile and run a small program which checks
whether result of getcwd() is DOS-style. In case of cross-compiling it just
knows that for DOS and MinGW native path style is DOS. Of course
config.cache value is taken into account.
 Technically it is possible to work around (2) using some clever heuristics,
but i don't see how it would be possible to determine whether e.g. /foo/bar
is an absolute path of DOS-style relative one.
 Will this solution be OK ?
