newlib/winsup/cygwin/exec.cc
Corinna Vinschen 117b1b1edb * dlfcn.cc (check_path_access): Drop FE_NATIVE from find_exec call.
(gfpod_helper): Drop equality sign from environment variable name
	in call to check_path_access.
	* exec.cc (execlp): Drop equality sign from environment variable name
	in call to find_exec.
	(execvp): Ditto.
	(execvpe): Ditto.
	* path.h (enum fe_types): Drop FE_NATIVE.
	(find_exec): Rename third paramter in declaration from search.  Drop
	equality sign from default value.
	* spawn.cc (perhaps_suffix): Add PC_POSIX to path_conv::check call.
	(find_exec): Simplify function.  Iterate over POSIX pathlist rather
	than Windows pathlist.  Drop handling of FE_NATIVE flag.  Always fill
	posix path of incoming path_conv buf, unless FE_NNF flag is given.
	(av::setup): Drop equality sign from environment variable name
	in call to find_exec.  Call unshift with normalized_path.
	* winf.cc (av::unshift): Drop conv parameter and code converting
	Windows to POSIX path.
	* winf.h (av::unshift): Accommodate prototype.
