[xdt-csource] main.c has found several typos while building in MinGW

The log of make is as follows:

main.c: In function 'main':
main.c:379:18: warning: implicit declaration of function 'g_local_to_utf8'; did you mean 'g_locale_to_utf8'? [-Wimplicit-function-declaration]

It seems that the g_locale_to_utf8 is misspelled as g_local_to_utf8.
