locale.h and gnuplot

[Jakson Aquino]

Hi Andreas,

Thank you for completing the code. Next time I send a
patch, I can make the changes. I think that the code
below now is correct, right?

#ifndef NO_GETTEXT
char * SX_saved_locale, * SX_old_locale;
#define SX_SET_LOCALE	\
	SX_old_locale = setlocale (LC_NUMERIC, NULL); \
        SX_saved_locale =
mymalloc(strlen(SX_old_locale)+1); \
	strcpy(SX_saved_locale, SX_old_locale); \
	setlocale  (LC_NUMERIC, "C"); 

#define SX_RESET_LOCALE \
	setlocale (LC_NUMERIC, SX_saved_locale); \
	free(SX_saved_locale); SX_saved_locale = NULL;
#endif


I think that we can put the above lines in statist.h.

Best regards,

Jakson
