Well, they're C libraries, so no namespaces, but the functions have 
different names. For each XXX function in the library:

* PCRE1 uses pcre_XXX for the 8 bit version, pcre16_XXX for the 16 bit 
version, pcre32_XXX for the 32 bit version;

* PCRE2 uses pcre2_XXX_YY with Y being 8, 16, 32 for the various versions.

So no harm done at mixing and matching.


(Side note, PCRE1 has reached EOL for quite some time now.)
