/* Semi-portable string concatenation in cpp.

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