The following code decides if the link should be a constant. (dbPutString in
dbStaticLib.c)
/* Check first to see if string is a constant*/
/*It is a double if strtod eats entire string*/
/*leading and trailing blanks have already been stripped*/
tempval = strtod(pstr,&end);
if(*end == 0) {
Thus it does not accept hex constants. Note also that recGblInitConstantLink
uses sscanf to convert from a string
to a numeric value. Thus just changing the above code will not fix the problem.
A possible fix is to have the above code try both strtod and strtol and if
either is successful then make the link a constant.
If recGblInitConstantLink uses "%i" for sscanf it looks like it should work.
Unless something unforseen arises I will make the changes for the next release
of 3.13 and 3.14.
