I use MSYS2. It indeed suppresses the warning, but with that code:

    char *name = "cmsy10.tfm";
    kpathsea kpse;
    char *n;

    kpse = kpathsea_new();
    kpathsea_set_program_name(kpse, "dvi.exe", NULL);
    kpathsea_init_prog (kpse, "dvi.exe", 300, NULL, NULL);
    n = kpathsea_find_file(kpse, name, kpse_tfm_format, 1);
    kpathsea_finish(kpse);

n is NULL.

If I replace "dvi.exe" with "kpsewhich.exe", n is filled with the correct value.

Any idea why ?

thank you
