[openssl-users] FW: problem with missing STDINT.H file

Tue Feb 7 19:56:07 UTC 2017

Thanks to all persons who have provided the expertise with my problem of missing header file. One suggestion was to step down a version to 1.0.2k. This has worked configure, make, make test and make install all executed and installed.

Using parenthesis with the defined and sizeof operators is considered good for readability and thus proper style in most projects.

What is a lot less readable in the if/ifelse/endif block that was posted is the somewhat counter intuitive order in which conditions are checked (and thus override each other).  That kind of complex logic often would benefit from comments clarifying the reasoning.  For example why is the workaround for UEFI located before tests for compiler support?  And why are all compilers claiming compliance with recent STDC versions assumed NOT to have stdint.h, only inttypes.h?

Enjoy
