Tom Lane 5a5c2feca3 Absorb -D_USE_32BIT_TIME_T switch from Perl, if relevant. ... Commit 3c163a7fc's original choice to ignore all #define symbols whose names begin with underscore turns out to be too simplistic. On Windows, some Perl installations are built with -D_USE_32BIT_TIME_T, and we must absorb that or we get the wrong result for sizeof(PerlInterpreter). This effectively re-reverts commit ef58b87df, which injected that symbol in a hacky way, making it apply to all of Postgres not just PL/Perl. More significantly, it did so on *all* 32-bit Windows builds, even when the Perl build to be used did not select this option; so that it fails to work properly with some newer Perl builds. By making this change, we would be introducing an ABI break in 32-bit Windows builds; but fortunately we have not used type time_t in any exported Postgres APIs in a long time. So it should be OK, both for PL/Perl itself and for third-party extensions, if an extension library is built with a different _USE_32BIT_TIME_T setting than the core code. Patch by me, based on research by Ashutosh Sharma and Robert Haas. Back-patch to all supported branches, as commit 3c163a7fc was.
