26 | /* Semi-portable string concatenation in cpp. | |
27 | The NLM_CAT4 hack is to avoid a problem with some strict ANSI C | |
28 | preprocessors. The problem is, "32_" or "64_" are not a valid | |
29 | preprocessing tokens, and we don't want extra underscores (e.g., | |
30 | "nlm_32_"). The XNLM_CAT2 macro will cause the inner NLM_CAT macros | |
31 | to be evaluated first, producing still-valid pp-tokens. Then the | |
32 | final concatenation can be done. (Sigh.) */ | |
