+ c-dtoastr, c-ldtoastr: new modules
+ These modules provide the same functionality as the modules
+ dtoastr and ldtoastr except for the formatting taking place in the
+ C locale.
+ * MODULES.html.sh: Add c-dtoastr and c-ldtoastr.
+ * lib/c-dtoastr.c, lib/c-ldtoastr.c: New files.
+ * lib/ftoastr.c: Prefix exported functions when the macro C_LOCALE is
+ defined. Use c_snprintf and c_strtod/c_strtold instead of
+ snprintf and strtod/strtold whhen the macro C_LOCALE is defined.
+ * lib/ftoastr.h: Add prototypes for c_dtoastr and c_ldtoastr.
+ * modules/c-dtoastr, modules/c-dtoastr-tests, modules/c-ldtoastr,
+ modules/c-ldtoastr-tests: New files.
+ * tests/test-c-dtoastr.c, tests/test-c-dtoastr.sh,
+ tests-c-ldtoastr.c tests-c-ldtoastr.sh: New files.
