#886 unknown type name 'USN'

[Rafał Brzegowy]

Hi,

When I try to compile double precision CalculiX (FEA program; -DLONGLONG) I have this error (standard version is OK):

<command-line>: error: expected identifier or '(' before numeric constant
<command-line>: error: expected identifier or '(' before numeric constant
<command-line>: error: expected identifier or '(' before numeric constant
<command-line>: error: expected specifier-qualifier-list before numeric constant
<command-line>: error: expected specifier-qualifier-list before numeric constant

and

<command-line>: error: expected specifier-qualifier-list before numeric constant

The problem is most likely only with these two files (CalculiX files): external.c and getSystemCPUs.c, only these files have a reference to: #include <windows.h></windows.h>

[Rafał Brzegowy]

I have the same error for such a simple example (example.c):

#include <stdio.h>
#include <windows.h>
int main() {
   // printf() displays the string inside quotation
   printf("Hello, World!");
   return 0;
}
