Both look like: while (isalnum((int) *p) || *p == '.' || *p == '-') p++; and for you need to look like: while (isalnum((int) *p) || *p == '.' || *p == '-' || *p == '_') p++; That will get it accepted, but there may be other checks elsewhere in the code. I haven't looked, but the above should get you started. I'm assuming that for such a large and important customer, you are able and willing to document and maintain local patches. -- "Everything has three factors: politics, money, and the right way to do it.
