-# $cflags - command line qualifiers passed to cc when preprocesing perl.h
-# Note: A rather simple-minded attempt is made to restore quotes to

+# $cc_cmd - compiler command
# $objsuffix - file type (including '.') used for object files.
# $libperl - Perl object library.
# $extnames - package names for static extensions (used to generate
# must be linked

# Output:
-# PerlShr_Attr.Opt - linker options file which speficies that global vars
+# PerlShr_Attr.Opt - linker options file which specifies that global vars
# be placed in NOSHR,WRT psects. Use when linking any object files
# against PerlShr.Exe, since cc places global vars in SHR,WRT psects
