patch 9.0.2180: POSIX function name in exarg causes issues
Problem: POSIX function name in exarg struct causes issues
on OpenVMS
Solution: Rename getline member in exarg struct to ea_getline,
remove isinf() workaround for VMS
There are compilers that do not treat well POSIX functions - like
getline - usage in the structs.
Older VMS compilers could digest this... but the newer OpenVMS compilers
( like VSI C x86-64 X7.4-843 (GEM 50XB9) ) cannot deal with these
structs. This could be limited to getline() that is defined via
getdelim() and might not affect all POSIX functions in general - but
avoiding POSIX function names usage in the structs is a "safe side"
practice without compromising the functionality or the code readability.
The previous OpenVMS X86 port used a workaround limiting the compiler
capabilities using __CRTL_VER_OVERRIDE=80400000
In order to make the OpenVMS port future proof, this pull request
proposes a possible solution.
