1099 such types, using defaults reasonable for the current language and

1101
1102 NOTE: This routine is obsolescent. Each debugging format reader
1103 should manage it's own fundamental types, either creating them from
1104 suitable defaults or reading them from the debugging information,
1105 whichever is appropriate. The DWARF reader has already been
1106 fixed to do this. Once the other readers are fixed, this routine
1107 will go away. Also note that fundamental types should be managed
1108 on a compilation unit basis in a multi-language environment, not
1109 on a linkage unit basis as is done here. */
