/* A problem turned up with PCRE_PRERELEASE, which is defined empty for
|
|
||||||
production releases. Originally, it was used naively in this code:
|
|
||||||
|
|
||||||
return XSTRING(PCRE_MAJOR)
|
|
||||||
"." XSTRING(PCRE_MINOR)
|
|
||||||
XSTRING(PCRE_PRERELEASE)
|
|
||||||
" " XSTRING(PCRE_DATE);
|
|
||||||
|
|
||||||
However, when PCRE_PRERELEASE is empty, this leads to an attempted expansion of
|
|
||||||
STRING(). The C standard states: "If (before argument substitution) any
|
|
||||||
argument consists of no preprocessing tokens, the behavior is undefined." It
|
|
||||||
turns out the gcc treats this case as a single empty string - which is what we
|
|
||||||
really want - but Visual C grumbles about the lack of an argument for the
|
|
||||||
macro. Unfortunately, both are within their rights. To cope with both ways of
|
|
||||||
handling this, I had resort to some messy hackery that does a test at run time.
|
|
||||||
I could find no way of detecting that a macro is defined as an empty string at
|
|
||||||
pre-processor time. This hack uses a standard trick for avoiding calling
|
|
||||||
the STRING macro with an empty argument when doing the test. */
